“With Teeth” Chapter 5

((click here to read on ao3!!))

Izaya is frowning down at his computer, his hands hovering above the keys of his keyboard, not moving. Next to him, Namie is typing away, a bemused little smirk on her face. She's enjoying this, clearly, and she's itching to say something biting.

“You're handling this better than I thought you would,” she says, her tone forcibly bored. Izaya blinks at her, lifting his hand to motion for her to continue. “Your little monster friend has a girlfriend now. He'll have less time for you, right? I assumed you'd be setting fires across the city by now.”

“You know what they say about assuming,” Izaya says breezily. “If anything, she's distracting him enough to leave me be.”

The chatroom is full of people chattering away about Shizuo and Vorona, who are spending a lot of time together, holding hands, exchanging glances, sharing beverages. It's sickening. Izaya feels vaguely nauseous just reading about it, but he thinks that's probably due to his insane schedule at the moment, and his lack of sleep. He keeps meaning to take a healing potion, but he forgets every time.

“Distracting. Right.” Namie types another response, fanning the flames of all the rumors circulating about Ikebukuro's hottest couple. Her smirk drops, and Izaya can't resist the temptation to dip into her mind, just a little, to see why she isn't enjoying this as much as she thought she would.

She's thinking of Seiji, of course, but also of Mika, and of Celty's head, and all the times she's been overlooked in favor of someone else. She thinks Shizuo dating Vorona is distasteful, because she's set on the idea that Shizuo must be fucking Izaya, and that's why he comes by so often. Izaya withholds a snort at that, and he graciously doesn't comment on the fact that Namie could probably have anyone she wanted, if she wasn't so obsessed with her own brother.

“Who cares, anyway?” Namie asks, closing her laptop. “The two of them together probably have conversations as interesting as watching paint dry. It's not worth even talking about anymore.”

“I couldn't agree more,” Izaya says, pushing away from his desk. He tilts his head at her. “Let's order out for dinner. My treat.”

“In that case, I'm craving something expensive.”

“Of course you are.”

***

Izaya is watching the sunset from a small window when he realizes he must have fallen asleep. He isn't at home anymore, and this is beginning to feel like the kind of dream he's been dreading to have lately, one where he knows Shizuo will show up at some point.

“Who are you?” A child's voice asks from behind him. Izaya turns, looking down at Shizuo, who is in a hospital bed, his arms wrapped, a brace around his neck. He's frowning up at Izaya, who sighs loudly before plopping into the vacant chair next to the bed.

“Oh, why does it even matter? You won't call me by my name anyway.” Izaya pulls his knees up to his chest and studies Shizuo closely. “You're here alone?”

“My family just left.” Shizuo looks up at the ceiling, seeming to decide that Izaya isn't a threat to him. “They used to stay with me a lot, but this happens all the time now, so they can't stick around as much.”

“I see.”

“I'll only be here one night anyway.”

“So who was it this time? Was it another fight?” Izaya asks.

“It's not like I wanted to fight.” Shizuo's eyebrow twitches. “I threw a swingset.”

“A swingset?”

“Yeah, but apparently it was bolted into the ground or something. Really fucked me up.”

Izaya can't help it. He laughs hard, curling into himself as he does so.

“Hey, fuck you, it isn't funny!” Shizuo snaps, but he seems to be trying not to laugh himself. “Well, maybe it was a little. The look on their faces was pretty funny.”

“Did you at least manage to hit them?” Izaya asks, still giggling at the mental image.

“No. Turns out all the time I spent lifting it gave them some time to escape.”

Izaya laughs harder. When was the last time he found something this genuinely funny? Lately all he does is work until he passes out, and he deserves it, he knows. Still, as he feels tears stinging the corner of his eyes, he thinks he feels good now, here with this kid version of Ikebukuro's monster. There doesn't seem to be anything else to do but talk to him, and their dreams keep connecting them no matter what Izaya does. He's tired of fighting it.

Shizuo is gazing at him with poorly concealed awe and wonder.

Pretty.

Izaya snorts at Shizuo's thought. What's so pretty about this scene right now? The sunset outside? The various machines hooked to Shizuo, beeping idly in the background? Shizuo keeps looking at him, and Izaya realizes, feels his face grow hot.

“Who are you?” Shizuo asks again.

“Your worst enemy.”

“Really? You don't seem all that bad.” Shizuo shifts a bit, winces. “You're not scared of me, are you?”

“Not now, not ever.”

Shizuo nods, and his lip wobbles. “People tell me all the time they aren't scared of me, but I know they are, deep down. How could they not be? They'd have to be crazy. But...” Shizuo chokes up, laughs a little. “I can tell you mean it. And if that makes you crazy, I think that's okay, because it feels good to not be feared, for once.”

Izaya lowers his legs, leaning closer to the bed. He idly touches the flimsy fabric of the blanket draped over Shizuo, who is watching him curiously. Izaya looks away.

“Sometimes you're so pathetically simple it makes me want to vomit. Sometimes it feels like a chore, hating you. Did you know that?” Izaya asks softly, and there's a long pause after his words, no sounds aside from their breathing. Even the machines have somehow gone quiet.

“So then why do you?” Shizuo asks at last.

“Isn't it funny that it's been so long of us hating each other that I forgot what caused it in the first place? I think you did, too.” Izaya crosses his arms over the bed, puts his head down. “People like us will always be at each other's throats. It's just the way it is.”

“You sound like a grownup,” Shizuo says, glaring now. “They always say that, when they don't know the answer to something. 'It's just the way it is.' If you don't know, then why does it matter in the first place?”

“Believe it or not, I am a grownup. I'm only a kid right now because you're one, too. We're always the same age in these dreams, even if only one of us remembers the future at a time.” Izaya lifts his head enough to grin at Shizuo, who blushes and immediately turns away. He seems to be trying to gather the courage to say something, but there's suddenly a knock at the door, and Izaya turns towards it. “Expecting someone else?”

“Huh?”

“There's knocking.”

“I don't hear anything.”

Izaya stands. “Oh. This may be in real life. I think I'm waking up.”

“Waking up? Does that mean leaving?” Shizuo's eyes look panicked. “When will you be back?”

“I never know. Why do you keep wanting to see me so badly? You're the one pulling me back here, you have to be.” The room starts to grow fuzzy as the dreamscape begins to fall apart around them.

“You're not scared of me. You laughed at me instead of running— Fuck!” Shizuo seems to be trying to get up to grab Izaya, but he can't with his arms bandaged. “Tell me your name so I can find you again!”

“You'll just call me a flea anyway, won't you? So it doesn't matter.”

***

Izaya opens his eyes to discover he passed out at his desk at some point. He sits up and frowns at the container of pasta next to him. He remembers ordering dinner for himself and Namie, and then...

“Ugh. Of course she just left,” Izaya mutters to himself. Namie is an opportunist if nothing else. She isn't the type to stick around and see what happens next, unlike Izaya. Another knock sounds at the door. “Who is it?” Izaya calls, feeling sluggish. He checks his phone to find he's been asleep for about two hours.

“Me!” Shinra's voice replies, muffled from the door. “Let me in, would you? I've been knocking forever!”

Grumbling, Izaya makes his way across the room, opening it for Shinra, who waltzes inside like he owns the place.

“Hi! I'm working late tonight, and I didn't have time to eat dinner before I left, so I figured while I was in Shinjuku I could come see what you had—“ Shinra stops talking and tilts his head to the side, observing Izaya. “You look awful. What have you been up to?”

“Also working,” Izaya says. He reaches up to wipe crusted drool from the corner of his mouth. “So you came to raid my fridge?”

“Ah, yes!” Shinra turns and continues his march to the kitchen. “I just got done with an emergency call, and next I'll be going to visit another patient. I didn't want fast food, so here I am! Did Yagiri-san make anything?”

“Should be leftovers somewhere around here.” Izaya looks back at his own pasta, feels his stomach rumble. He can't remember the last time he really ate or slept fully.

“Why don't we eat something together?” Shinra asks. “You look ready to fall over.”

Izaya ends up tossing the pasta. It was congealed together, and not very good in the first place. Namie picked the place to order from, but he'll definitely complain enough about it later to where they don't order from there again. Shinra actually goes through the trouble of throwing together some fried rice, because Izaya doesn't have the ingredients for much else. He'll have to send Namie for groceries.

“So what are you working on so religiously, anyway?” Shinra asks as they sit down. “I haven't seen you this absorbed in work for a while.”

“It's not just one assignment, but multiple. All of them are due around the same time.” Izaya eats a bite of rice and shrugs. “It's just poor timing.”

“More than that though, right? I heard Shiki-san was pissed at you for multiple reasons. Sounds like he's keeping you overloaded on purpose.” Shinra smirks at him. “You can never leave well-enough alone, Izaya-kun.”

“'Well-enough',” Izaya scoffs. “If he had his way, I'd be locked in a cage, of use only to him and his little cronies.”

“That's what you signed up for. You'll get yourself killed if you keep meddling. I mean, come on, Akane-chan? What did you think would happen by sending her off on her own like that?”

“Who says I was behind any of that? Akane-chan has a smartphone. Kids like her are always going to be involved in things, because they want better than they're given.”

“I don't believe you, and I know Shiki-san doesn't, either. It's clear he's punishing you, but...” Shinra leans closer, lowers his voice like he thinks Shiki is in the next room. “To be honest, I thought you'd have it way worse than this. You ordered Shizuo-kun's attack too, didn't you? I thought Shiki-san would hang you upside-down.”

“Again, Shinra, you're reaching way too far. I never said I was responsible for Shizu-chan either.”

Shinra pouts, and then sits back in his chair, shoveling down more rice. “Fine. Don't tell me. Just take better care of yourself, at any rate. It's not like you can't cure the effects of fatigue with your power. You're choosing to suffer, right? But then again, you've always been like that.”

“Don't you have another appointment soon?” Izaya asks, annoyed by Shinra and his big mouth. He's often wondered if friendship is supposed to be this exhausting, but it isn't like he has anything else to compare it to. Shinra was always the only one crazy enough to stick around.

“I'm only saying. You should accept your punishments and actually learn something from them every now and then. It seems like you just bounce back, more determined to make a nuisance of yourself than before.”

“If I don't make a nuisance of myself, I'll die from boredom,” Izaya lilts. “It's really that simple.”

“More like you're worried about being forgotten.”

Izaya resists the urge to throw something at Shinra, who is wearing a strange expression, something akin to actual concern.

“You've improved on your acting ability,” Izaya says, pushing away from the table. “Don't act friendly towards me now. It doesn't suit you.”

“I am your friend,” Shinra insists. “I'm the only one you've got, so maybe you should listen to me once in a while.”

“It always goes back to Celty anyway. What, are you worried I'm going to use her for something too dangerous?”

“Celty agrees with me that it's unusual for you to allow Shizuo-kun to be in your space as you have. Are you actually feeling guilty?”

“Are you?” Izaya stands and grabs a bottle of red wine from his counter before he pads over to his desk. “I don't have the time for this, Shinra. See yourself out when you're ready to go.”

Shinra sighs loudly, finishes his dinner, and picks up his briefcase. He walks towards the door.

“Take care of yourself, Izaya-kun. If you even know how to.”

Izaya uses his magic to slam the door shut behind Shinra, and then he drinks until he passes out.

***

He wakes hours later, in bed somehow.

Groaning, he sits up, trying to remember the night before. His mouth feels like cotton, and his head feels like it's trying to split itself open. He thinks he may throw up at some point in the very near future.

“Feeling better?” Tsukumoya asks from beside him. The shades are drawn closed, and the room is still dark despite the sun being out. Izaya glares at the vampire in his space.

“Why are you here?” he croaks.

“You don't remember? You invited me. We fucked.” Tsukumoya has his laptop, and is typing ridiculously fast even as he speaks. “It was quite the evening.”

“I'm serious. You just keep popping up. It's annoying.”

“Mm. I had a feeling you were being your usual destructive self. There's water for you on your nightstand.”

Izaya reaches next to him, grabs the glass before chugging it. His stomach immediately churns dangerously in protest.

“Why not take a healing potion? I know you have plenty of them,” Tsukumoya says, still not looking at him.

“Don't need it.”

“Right, you don't. The great Orihara Izaya doesn't need anything or anyone, how could I forget?” Tsukumoya finally glances over at him. “You might need to reconsider. Tonight's the night of the full moon. You'll need to be alert when your puppy visits.”

“Fuck, is it? I forgot all about it.” Izaya groans and flops back into the bed, rolling away from the annoying vampire in his space. “You weren't supposed to come until tomorrow.”

“Stop complaining so much. Do you need more water?”

Grumbling, Izaya tries to piece together the night before. He drank too much, he remembers that. Shinra was being annoying. He definitely fell asleep at his desk, meaning Tsukumoya carried him to bed.

“We didn't really fuck, did we?” Izaya asks.

“No. Did you want to?” Tsukumoya's voice is annoyingly smug. “I wouldn't be opposed.”

Izaya snorts and closes his eyes, wills the room to stop spinning. “Don't flatter yourself. You're not my type.”

“I'm not? Here I thought you had a thing for monsters.”

Izaya considers throwing Tsukumoya across the room, but that would be rising to the stupid teasing, and it would require more effort than he currently wants to exert. He stays where he is, listening to the sound of Tsukumoya's fingers on the keys.

“You're being especially pitiful lately, Izaya,” Tsukumoya says after a while. “So you've lost control of your little game, so what? Maybe you should think of what to do next instead of working to the point of exhaustion. You know I hate it when you're predictable.”

“Why does it matter what I do? I'm trapped.”

Tsukumoya sighs. “Yes, you are. And what are you going to do about it?”

“Right now, I'm going to be miserably hungover. Next, who knows? It'll surprise us both.”

“If only I found you sooner.” Tsukumoya goes back to typing. “The things you could've done. Humans are always finding ways to control what they don't understand or fear. But now, you can only help yourself. If you believe you're going to be trapped forever, they've already won.”

“I know that.” Izaya thinks of the work assignments that aren't ever going to stop, and he thinks of Akane, of Shizuo. He knows he went too far, but he has to go even further still.

Tsukumoya seems like he wants to say more, but he pauses, and the typing stops once more.

“You really might want to take that potion now,” he says. “One of your executives is on his way here.”

***

Izaya does not take the potion, and when he answers his door, it's with a slightly green complexion. Akabayashi takes one look at him, and promptly bursts into laughter.

“Oh, wow. And I thought I drank too much. You look awful, brat.” Akabayashi invites himself inside, stepping around Izaya. “I'm doing a wellness check on behalf of the boss. You understand, right?”

“Seems like I have more people in my life than I thought,” Izaya says, closing the door before moving to his couch. “This is my third wellness check.”

“Hard to believe a roach like you has friends, but then again, this city has an infestation. You missed a deadline today.”

“I got a little carried away last night. I've been in bed all day.”

“But you answered the door fully dressed, like you've been up and about,” Akabayashi presses.

“I sensed you coming,” Izaya lies.

Akabayashi hums in thought, and he grins menacingly. “Ya know, I ran into Heiwajima the other day at Sunshine. He seemed really interested in who bit him and why.”

“You should tell him,” Izaya says. “If anything, it would get him off my back for a while.”

“Oh, don't act innocent. We all know who made the phone call that started everything.”

“Clearly what I want doesn't matter. You've made that abundantly clear.”

Akabayashi walks closer to the couch, and he leans closer to Izaya. “Watch yourself, kid. Just because you haven't been caught in the act yet doesn't mean we don't know you're guilty. That magic of yours will only get you so far with us.”

“If your power spans so far, you shouldn't be worried about what I did or didn't do. If you really knew I was guilty, you'd have killed me by now,” Izaya says.

“Assuming monsters like you actually have enough humanity left to die.”

“Why don't we both find out?”

They glare at each other, and Izaya can sense from Akabayashi that the executive would like nothing more than to tear him limb from limb, but he won't. It would be against Shiki's wishes, and as much as Akabayashi hates it, he has to follow orders, or he'll be next on the chopping block. He takes another step towards the couch, but before he can do or say anything, the door slams open with such force that it bangs against the wall and cracks it.

“Hello, Shizu-chan,” Izaya calls without breaking eye-contact with Akabayashi. “Entertain yourself for a moment, will you?”

“What the fuck is this?” Shizuo asks. He growls when he notices Akabayashi. “Oi! I still have questions for you, asshole!”

“I'm sure you do,” Akabayashi says, standing up straight again. He grins at Shizuo. “I can't answer 'em for you, though. Sorry about that.”

“I could always beat it out of you,” Shizuo says, cracking his knuckles. “I'm even stronger than I used to be, since you bastards made me into a monster.”

“You wouldn't get far. I'd relax, if I were you.” Akabayashi turns back to Izaya. “Get to work, brat. Shiki's only so forgiving.” With that, he turns on his heel, and goes towards the door. Shizuo makes to stop him, but Izaya lifts his hand and summons Shizuo backwards, towards the couch.

“What the fuck!” Shizuo shouts, fighting it. “Let me go!”

“Don't make me exert myself, Shizu-chan. I'm having a rough day,” Izaya says. Shizuo turns and glowers at him, but his features soften.

“What's wrong with you? Are you sick?”

“Yes.” The door opens and closes, and Izaya knows he's alone with Shizuo once more. “You didn't knock this time.”

“Didn't think I needed to. It's not like you weren't expecting me.” Shizuo leans down, scrutinizes Izaya. “You're hungover.”

“Don't read my mind,” Izaya huffs, curling into himself.

“I didn't. You reek of alcohol.”

Grumbling, Izaya summons a blanket and throws it over himself. He doesn't know if he prefers Tsukumoya's company to Shizuo's, but at the moment, he thinks he'd rather deal with the vampire. At least for a little bit.

What a messy flea. Shizuo thinks, and then he walks away from the couch. There's the sound of him sifting through the fridge, but there isn't anything for him to find. Namie had the day off, and Shinra cooked what little was available the night before.

“You might have to order out,” Izaya calls. “You have a couple of hours before sunset.”

Shizuo growls loudly, thinks something about Izaya being useless, and then pulls out his phone. Izaya stays where he is and doesn't move, enjoys the silence for a few moments before it's ultimately shattered by Shizuo, who is suddenly sitting on the couch near Izaya, but still far enough to where they're both comfortable.

“I ordered pizza,” Shizuo says, and he leans back against the couch cushions. “You should foot the bill.”

“If you wanted me to pay, you could've ordered something better,” Izaya replies.

“Nah, everywhere else would've taken too long. Pizza is fast and easy.”

Izaya watches sleepily as Shizuo picks up the remote and turns the TV on, flipping through a few channels before settling on a soap opera. It should feel weird, sitting here with Shizuo, watching a woman sob because she caught her husband having an affair, but it really doesn't feel weird at all. Maybe Izaya is too tired to feel one way or another about it, or maybe their strange mental link has done the majority of the work in making them civil towards one another. Either way, Izaya feels comfortable enough to let his guard down a little, and it's an instant relief, like setting down something immensely heavy.

“So, I don't get it. Why are you just sitting here feeling like shit when you can heal yourself easily enough?” Shizuo is still looking at the screen, but he's back to poking around in Izaya's head, whether he knows he's doing it or not.

“Shut up, Shizu-chan,” Izaya says without any real bite.

“Oh. You just want to feel bad. Seems like a stupid thing for someone who's supposed to be some kind of genius, but whatever.”

The woman on screen is confronting her husband's mistress, and it winds up in a fist fight on a balcony. Izaya snorts when the mistress is pushed off to her death. How predictable. Shizuo is scowling at the TV, but he's thinking about his shared dreams with Izaya, and also about some images he's been seeing through Izaya's side of the link. He's also thinking about Shinra, who apparently ran into Shizuo last night after his last appointment. Shinra seemed worried about Izaya.

He's a good actor. Izaya sends. He always has been.

I don't think he was acting. You look worse than you normally do.

I'm hungover, as you so aptly put it. You being in my head isn't helping me feel better.

“I'm not doing it on purpose!” Shizuo snaps, and the sudden loudness has Izaya flinching. “I don't get why it's happening either, okay? I'm only just now starting to believe it's not actually you doing it.”

Because you've seemed like such a mess ever since it started. Shizuo thinks, and Izaya grinds his teeth in frustration.

“I'm not a mess.”

“What did that guy want?” Shizuo asks, changing the subject abruptly.

“Akabayashi-san stops by from time to time to threaten me. It's a pastime for him.” Izaya is starting to feel nauseous again, so he closes his eyes and wills it to go away.

“Don't you work for him, though?”

“I don't work for anybody. I'm a freelance informant for hire, and I give the organization he's part of information when they pay me for it, same as anyone else.”

Shizuo frowns, thinks something biting about Izaya working for the Yakuza. “He seemed like he wanted to hurt you.”

“Oh, he does. They all do,” Izaya says. “They'd kill me if they could.”

Shizuo doesn't like that he has something in common with the Yakuza. He grimaces before he says, “So what? You're just too strong to die or some shit?”

“No,” Izaya replies. “I'm just too important for them do dispose of. I'm part of the reason they're as powerful as they are, and they know it, even if they hate it, even if they hate me. I'm the strongest tool in their arsenal. Killing me would be crippling themselves.”

Silence follows Izaya's words. Shizuo's mind is a whirlwind now, thinking so many things at once, all laced with rage. He doesn't like anything about what Izaya said, the way it was said so flippantly, the way Izaya doesn't seem to mind. Shizuo doesn't like that Izaya thinks of himself as a tool, as something other than human, even if it might be true. Shizuo doesn't want to think of himself as other than human, either.

Shizuo doesn't seem to do well with the truth.

“That isn't true,” Shizuo growls, no doubt in response to Izaya's thoughts. “You're a person. I'm a person. We're other things too, but whatever we are, we're human first. You said so yourself, right? You can die, you can be killed. You're human enough to die.”

“I'm telling you this once, and once only, beast,” Izaya murmurs, opening his eyes to glare at the TV as he speaks. “It would be the exact same as breaking a screwdriver, or losing your favorite toy. If I died, that would be it. They would just replace me. They want to, and they would if they could, but I'm one of the last of my kind, and I'm definitely the most powerful one left. I don't care about it, because I've always known I was only useful for what I knew and what I could do. If you're going to be hated, you damn well better be useful. That's the way it is.”

“Fuck that!” Shizuo yells, and he stands, his hands clenched into fists. “What the hell are you talking about? You think it's okay to sit here and feel sorry for yourself, like you didn't have a hand in being the hated little rat you are? You think it's just because of your magic? You're the one deciding to do the shitty things you do. People hate you. If they knew you were a witch, whatever, maybe some of them would hate you more, but it's only because they hate you already. Get the fuck over yourself.”

Izaya laughs, delighted at the outburst. Doing so hurts his head, and his vision swims. This is pitiful, isn't it? Feeling useless, being forced to lie back and swallow vomit just so no one else can ask anything more of him. If he's a tool, he's a damaged one, and every time he's human, he dulls himself a little more. If this is a game to be played, and his opponents have the winning hand, Izaya will make sure none of them win. He'll destroy himself if he has to. He'll destroy everything.

“Trust me, Shizu-chan,” he croaks, “I know they would've hated me either way. The difference between us is you're searching so hard for a place to belong, and I've accepted long ago that it doesn't exist. Now would you kindly shut the fuck up? My head hurts.”

Shizuo is seething, his breaths labored as he works to calm himself down. He wants to lift Izaya up and shake him until his head pops off. Then Shizuo wants to tear apart everything in the apartment, maybe go punch Akabayashi for good measure. He hates that he sees the reasoning in Izaya's words. He hates himself, and he hates Izaya more than anything else.

“Get out of my head,” Shizuo grits out.

“I'm trying,” Izaya says, and he leaves it at that.

They lapse back into silence, and when Shizuo flops back onto the couch, his brow is furrowed, his jaw set. It's clear he isn't going to let this go, but he at least doesn't want to be in a terrible mood before his transformation. The bloodlust is worse when he's angry. He has to keep reminding himself that Izaya is a liar, first and foremost. Izaya uses words to protect himself, and Shizuo doesn't have to, and won't, ever do the same.

“Well, isn't this cozy?” Tsukumoya's voice asks as he walks down the stairs. He's wearing a hood, covering himself from the weakening rays of sun that still shine through the windows.

“I thought you left,” Izaya calls as Shizuo whirls to growl at the vampire.

“I was going to, but I figured I'd stick around to make sure you didn't die,” Tsukumoya says. He smirks at the scene of Shizuo and Izaya sitting together almost peacefully, watching trash TV in silence. “I wondered how your nights with the puppy went. I suppose I can see for myself now.”

“Why the fuck are you here?!” Shizuo barks, and then he whirls to face Izaya. “Does he always just pop up like this?”

“Not always,” Izaya says. “He stayed the night.”

“What?”

“Relax, Heiwajima-san. Rest assured, I didn't touch him.” Tsukumoya flounces past the couch while Shizuo's face turns a variety of fun colors. “At least, not much.”

Shizuo stands from the couch, and Izaya sighs loudly.

“Don't you have anything better to do?” he asks Tsukumoya, who is still looking at Shizuo appraisingly.

“Yes, as a matter of fact, I do. I trust you won't drink yourself stupid a second night in a row?” Tsukumoya says, looking at Izaya.

“I don't have the luxury tonight,” Izaya answers.

“Right, you're puppy-sitting.”

“Do you mean me, you fucking—“ Shizuo starts, and he barrels towards Tsukumoya, who easily side-steps him.

“Make sure you eat something at some point,” Tsukumoya calls to Izaya. “That pizza will help you feel better.”

“I don't want it,” Izaya grumbles, covering his head with the blanket. He hates both of the people in his space right now, and he just wants to sleep.

You must be making a conscious effort to not heal yourself if you're still this sick over a hangover. Tsukumoya's voice sounds in Izaya's head. Is this really helping anything?

Yes. Izaya can't escape either of them, can he? They're both annoyingly perceptive and persistent. He can feel fondness radiating from Tsukumoya, but it's quickly being overshadowed by the amount of fury pouring from Shizuo, who is clearly listening to their mental conversation.

“Your pizza is here,” Tsukumoya says, and the knock comes a moment later. “Make sure he eats something, please,” he says to Shizuo, and then he vanishes before anything else can be said.

***

Shizuo scarfs down the entire pizza at breakneck speed, once or twice trying to get Izaya to accept a slice before giving up. He doesn't care if Izaya eats or not, and he doesn't care if Izaya feels sick or not. Shizuo's mood increases as he eats, and by the time he's finished, he's as mellow as he ever is while sharing a space with his mortal enemy.

Izaya, for his part, is starting to feel a little better. His stomach rumbles a bit at the scent of the pizza, but his appetite wanes at the grotesquely barbaric way Shizuo eats. It seems worse than usual, more...animalistic.

In fact...something seems off about Shizuo, even for a full moon. Maybe something happened earlier, or maybe Shizuo just went too long without eating until now, but Izaya can sense the bloodlust permeating from Shizuo like a miasma.

“Shizu-chan,” Izaya says, slowly sitting up to level his gaze at his unwanted guest. “Have you taken your potion?”

“Huh? Of course I have,” Shizuo replies. His hair is glowing from the fading rays of the sun as it descends behind the tall buildings outside.

“Have you taken it exactly as you should, the way I instructed?” Izaya asks through clenched teeth, already knowing the answer.

“Well— I drank it all a couple of days ago. I spent all day with Vorona, and I didn't want—“ Shizuo pauses at the look on Izaya's face. “What? What did I do wrong? You said to take it all before the full moon, and I did!”

“I told you to drink it every day, bit by bit, and to finish it before the full moon. The exact way you've done every month until now, because you're so pathetic in the presence of that woman that you can't follow basic fucking instructions!” Izaya snaps, and Shizuo's eyes widen.

He looks scared. Shizuo thinks, and then a beat later, Oh fuck. He's scared of me.

“Izaya, I—“ Shizuo begins, and then his hands grip his knees as his body begins to shake. The sun's rays fade at last, bathing them in twilight. “I feel...wrong.”

Izaya stands from the couch, the room spinning as he does. He's not at his full power. Even if he weren't hungover, he hasn't been eating or sleeping the way he should, buried in work as he is, and reluctant to care for himself as ever. He starts towards the stairs, in search of the healing potion he should have taken earlier, but he knows it's already far too late, as Shizuo's body is already beginning to crack and twist, and his mind is already gone, replaced by that of a true monster.

“Shizu-chan, you're such a fucking idiot,” Izaya hisses, and his sentence is barely finished before Shizuo is lunging at him, aiming for his throat.
