Katsuki Bakugo wasn’t an undisciplined person in any way and anyone who had ever spent more than five minutes with the man would know it, back at UA his classmates knew it. His attitude and showmanship justifiable by his actions: hard work, determination to be the best at anything, unwavering confidence. So, it was no surprise that when he was presented with something that made him nervous, left him restless in bed having only gotten around five hours of solid sleep (unacceptable), that he dove head-first into internet research into hybrids, into the rescue facility itself – any reliable informative source Katsuki could get his hands on... he devoured all with a ravenous mind.  

He learned that there is a largely biological difference between hybrids and those with an animal quirk. He learned that there are hybrids of different biological levels – some he learned were bred or trained to lean more into their animal natures, while others acted similarly to those with animal quirks (largely human with animal likeness or simple qualities) – the bigger difference being they were still highly susceptible to the whims of their animal DNA (i.e., still driven by instinct, still at the mercy of their biological clocks as present in their hybrid DNA in regard to migratory urges, mating patterns... things of a more engrained nature). He knew now that something he needed to consider was what would be best for him – a hybrid that, like TetsuTetsu was fiercely like his hybrid side but if you didn’t notice the ears and tail at first would just mistake him for a high-strung human, or one that while appearing mostly human would be more aligned with their animal side internally – Katsuki decided he’d wait and see what was suggested at the meeting he had set for later in the evening at the rescue facility. He read up on the efforts of the facility and was nothing less than impressed by their work to rescue, rehabilitate and facilitate safe adoption for their hybrids, but also all of their compiled free resources to learn more about anything one could think of in regards to hybrids, as well as offering in-person classes to be exposed further to important topics and nuances of hybrid life and ownership – classes, Katsuki noted, he would have to take before being chosen to take home a hybrid.

The rest of the morning was a blur of Katsuki half in, half out of consciousness due to his lack of sleep. He moved around the house way too fatigued but managed to make a simple stir-fry in the morning just to get something into his body, and later giving in to his needs and taking a two-hour nap before waking up to shower, and get ready for the first meeting at the rescue facility to get the process started... and though he held a lot of uncertainty he was also looking forward to something like this – something that might help him not feel so alone. 

˗ˋˏ ♡ ˎˊ˗

Katsuki was just half-watching a street food documentary series when he heard his phone ping! with a message notification.  

3:37 P.M. [Shitty Hair] Hey dude! TetsuTetsu and I are on our way to pick you up... he wanted to come and see some of his friends.

3:39 P.M. [Blasty Boy] Whatever as long as the rockhead doesn’t drool on me.

3:45 P.M. [Shitty Hair] Awe are you wanting to make a good first impression Bakubro? So cute~

Katsuki slammed his phone down, a burning pink tinge to the tips of his ears as he grumbled to himself at the last message.  

He just didn’t want to look dirty for the interview.

Another hour had passed before Kirishima finally texted that he was down in front of Katsuki’s building waiting for him, which prompted the blonde to thumb through the folder he had with all the requested documents, glancing at each page for the fifth time again before deciding he hadn’t forgotten anything. He threw on a well-worn leather jacket over his casual outfit and stepped into his boots, taking a final look behind him before stuffing his wallet into his pocket where his phone already sat, and heading out the door with a final click of the automatic door lock.

In the elevator his body felt like a can of compressed air thrown into a fire – ready to burst – but he just took in slow breaths (agency sanctioned therapy) and as he reached the lobby and made his way out, he walked toward the dark sportscar that awaited him, seeing the back window rolled halfway down with TetsuTetsu’s excited face glancing around at the few people on the street until he saw Katsuki.

“Hey, heeeey! Bakugo!” TetsuTetsu was shouting out the window at the man’s approach and Bakugo simply rolled his eyes at the annoying display. Opening the door and sliding into the front passenger seat just as TetsuTetsu was shouting another round of greetings out the window at him.

“Shut up ya damn brick head!” Bakugo growled out, “don’t you have a damn shred of self-control?”

“Plenty!” TetsuTetsu replied, sitting back against the seat with an excited bounce, nearly jumping out of his skin to see Bakugo... even if he just saw him last week.

“Tch,” Bakugo scowled, but Kirishima picked up on the slight quirk to the corner of his friend's lips as he pulled the seatbelt across his chest. “Dumbass acting like he hasn’t seen me in years.”

“Ready to go, dude?” Kirishima beamed at his friends who only answered with a quiet grunt. The drive to the facility was about 45 minutes from Katsuki’s apartment, and he took notice of how the further they drove the scenery changed so drastically for such a short distance. Larger skyscrapers and bustling paved streets giving way to more rural, residential areas until he saw the large facility come into view. Katsuki had been in this area before but never noticed the expansive property even one time. It was partially hidden behind rows of trees, and there was a long, looping driveway to reach the front of the facility.  

“TetsuTetsu and I come here to volunteer a lot,” Kirishima finally broke the silence from the ride, “he likes to come and see some of his friends and socialize, and I help as an acting liaison since a lot of hero work does include rescuing hybrids either from disaster zones, or worse situations.”  

“I never knew that,” Katsuki added, though he had his share of hybrid rescue situations, he never once contemplated where they went after they were taken away – he wondered if they all came to a safe place like what was before him. “Also never knew that you had so much damn free time on your hands to come play around with puppies and shit...” Katsuki walked past the doors as they parted automatically, Kirishima laughed, walking behind him with a shit-eating grin knowing his friends was playing his emotions off cooler than he was feeling. Knowing what he knew of his friend, he was more nervous than anything and that made Kirishima hopeful for Bakugo’s recovery. Whatever that future held, he was certain, as he watched his friend’s back while he walked toward the center desk where a staff member was waiting to greet them, that he wouldn’t be alone and everything would be okay.  

Knowing Bakugo, he knew it wouldn’t be an easy process – but he could see the future becoming a brighter shade with each step.

“Ah, welcome back Red Riot!” The staff member beamed excitedly, “and welcome Mr. DynaMight!” She added, “and our little TetsuTetsu! Look how big you’ve gotten!” TetsuTetsu had a smile that took over his whole face as he puffed out his chest at the praise, allowing the woman to give a scratch at the top of his head between his tall ears.

“Alright Bakugo, you’re in good hands with Hina! TetsuTetsu and I are going to be in the common area, we’ll probably see you later once you’re given the tour. Text me if you need anything!” Kirishima was being dragged off by TetsuTetsu who was excitedly going on about who he wanted to see, his silver tail wagging so fast it blurred behind him. Hina got Bakugo’s attention, walking away to lead him toward the meeting room where he was going to be interviewed by the director, go over the paperwork and make copies of the documents he brought, thankful that this was all laid out in the call when he made the appointment – Bakugo liked to be as prepared as possible walking into new situations.

Hina had dismissed herself as she showed Bakugo where he could grab a snack or coffee, tea, water – she offered him everything even as he declined, certain anything that would go into him at this moment would come right back out. He was told the director was running a bit late but should be with him in about ten minutes. He was fine to have the room to himself to calm down, he could feel his palms slickening the more anxious he got and the last thing he wanted to do was blast the damn director with a handshake.

Maybe he did want that tea.

˗ˋˏ ♡ ˎˊ˗

Across the facility in the common room Kirishima was crowded by his normal little friends, excitedly saying hello and telling him about their recent activities since his last visit. His eyes scanned for TetsuTetsu he noticed was frozen to the spot where in stood just in the doorway that led out to the garden. He followed the hybrid’s gaze to a small puppy hybrid curled up underneath a tree bathed in speckled sunlight. Kirishima watched as TetsuTetsu walked out into the garden with tentative steps and saw the puppy hybrid’s wide eyes shoot up toward him.

What a beautiful little creature.

He took in how small you were compared to most other hybrids he’s met so far (aside from the very smallest types), noting that you would definitely only come up to just under his chest, similarly compared to Bakugo a few inches higher on him at the center of his chest - maybe. Your ears were tall points atop your head, and the large, fluffy tail behind you started to give slow thumps as you watched TetsuTetsu approach. Kirishima observed his hybrid sit and pull you into his lap, rubbing his cheek atop your head and watching as your body shook a little, light catching a glistening on your cheek just before it was thumbed away. You shook your head, palming away the tears before giving a beaming smile up at TetsuTetsu whose tail was wagging wildly looking down at you, but Kirishima could see it.

The way the smile didn’t reach your eyes.

He spent more time with the hybrids gathered in the common room, always keeping an eye on his hybrid and the new little companion. Kirishima was soon being pulled multiple ways by hybrids and staff alike to help where it was needed getting lost in the bustle of what normally came with spending time at the hybrid facility – work. It was a brief moment when his eyes darted back out into the garden where he didn’t see you or TetsuTetsu that Kirishima’s whole body went cold with nerves before he settled himself, knowing that even if you both wandered the place you were in was safe. He just always felt better having eyes on TetsuTetsu since he brought him home. It was when he heard a familiar laugh that he noticed you both sitting in front of a T.V. watching Pro Hero fights, TetsuTetsu exclaiming loudly at each incredible move, and you curled up into TetsuTetsu’s lap looking so contented just to share space with someone. Kirishima decided to walk over and introduce himself, but with the way he noticed your eyes always darting around, watching the way your body jumped – just slightly – at each louder than normal noise... he knew he had to approach you carefully than most.

“Hey buddy,” Kirishima called out, lowering his normal boisterous tone to a gentler level, “what’cha watching?”

“Ah Eijiro! Look, look, look!” TetsuTetsu almost threw you out of his lap if he didn’t have an arm hooked around your body holding you to him. “It’s an old Fourth Kind fight!” TetsuTetsu’s tail was whipping behind him with a furious thump seeing the fight. You were leant against his chest with your cheek squished by his shoulder as your eyes studied the huge red-headed Pro standing nearby. Kirishima gave you a bright smile but noticed the way your eyes widened, he wondered if it was the sharp teeth or just being noticed by someone new, he kept his eyes on you with a kind expression on his face as he got TetsuTetsu’s attention back, “Hey bud – who’s your little friend?”

“Ah!” TetsuTetsu tightened his grip on you as he turned his body slightly to show more of you. “This is Tiny!” Kirishima knelt down on the floor, squatting with his butt against his legs to be less of an impending sight to you.

“Tiny huh? Is that really your name?” Kirishima kept the smile on his face, kept his tone gentle and noticed the way you shook your head slowly, but then shrugged – TetsuTetsu popping back into the conversation with a quick, “I call her Tiny because she is! Also, because she said she didn’t have one...” TetsuTetsu trailed off, attention being piqued again by the Pro Hero fight on the T.V. but Kirishima and you were having a staring contest, your ears and cheeks dusted a light pink as you rested your chin on TetsuTetsu’s shoulder.  

“If it’s okay to ask,” Kirishima wanted to grab you from his hybrid and curl you up in his arms himself with how cute you looked at the moment, but knew he had to swallow down those feelings. “You don’t have a name?”

“Mm,” you shrugged, “not one I care to have.”

“Have you ever thought about choosing one for yourself?” Kirishima tested the waters, and it seemed you relaxed more around him now than when he first walked over, but you still stole tentative glances at TetsuTetsu for reassurance.

You slowly shook your head, “not really – not if everyone is gonna call me something different anyway.”

The way you said that made Kirishima’s blood turn, but he didn’t let it affect his interaction with you, opting to keep the smile and calm demeanor going, “What do you like to be called most?” Kirishima saw you falter for a moment, probably never having been asked that question before.

“I like when Tetsu calls me Tiny,” the warm smile lit up your face so beautifully, “and almost everyone else I know just calls me Puppy because... I’m a puppy, or really lots of other names too...” your voice got softer a trailed off at the end. Kirishima could see something brewing behind your eyes but didn’t push it further as you rubbed behind your neck a little nervously.

“Is it okay for me to call you eith-” Kirishima could get his full sentence out before you just grinned widely and nodded your head.  

“M’okay with anything if it isn’t mean,” you say softly, and Kirishima thinks his heart is going to explode.

˗ˋˏ ♡ ˎˊ˗

Across the facility at the tail end of the interview Bakugo thought his heard was going to explode just the same.

“Well, Mr. Bakugo I’m thoroughly impressed with how you’ve answered my questions, and asked your own,” the facility director was thumbing through her own notes and the documents Bakugo had brought with him ensuring all was in order. “I’ve never had an adoption prospect be as informed and prepared as you’ve made yourself which is wholly impressive and says so much about how you’d go into owning a hybrid – truly impressed,” the woman was nodding and repeating herself but Bakugo wasn’t hearing a definitive yes to moving forward so he kept waiting with bated breath. “I’d like to take you for a tour of our facility and tell you more about our efforts, and what you can expect moving forward in this program, and we can meet some of the hybrids who are probably out wandering in the common room at this time as well.” Bakugo simply nodded in a daze, heart rate starting to slow back to a normal pace as he started to collect himself, following the director out of the meeting room and into a long stretch of hallway as she went on about the facilities history and all of what they offer for the hybrids in their care – all information Bakugo had read up on but hearing it as he toured the grounds was still enlightening.

Upon reaching a more open area that the director called the common room he took in the mild bustle of the room, hybrids of all types wandering, lounging and laughing with each other and staff alike.  

“So, this is our common area where a lot of the hybrids who are suited for group environments come to socialize and spend their time,” the director drew Bakugo’s attention to the gorgeous garden they had, as well as a small food garden run by some of the facilities bunny hybrids who also helped out in the kitchen – they were a little skittish but super still super kind to show Bakugo around their garden. He also met a few wolf hybrids like TetsuTetsu, a cougar, two cats and a koi fish hybrid lounging in a large, open clearwater pond on the far end of the garden but what really caught Bakugo’s attention was on the other side of the garden in a separate part of the common room – more hybrids were lounging around at tables, but in front of a T.V. where old Pro Hero fight tapes were playing he saw Kirishima’s too large body sunk into a bean bag chair with TetsuTetsu curled up against his side, with a smaller form squished between them, mostly on Kirishima’s chest, nuzzled into his neck.

“Oh - that’s a sight that makes me happy,” the director sighed, sharing the same sight Bakugo was taking in. “That’s our newest hybrid, though she originally came to us just a short while before TetsuTetsu did she was also adopted out shortly after Mr. Kirishima took our TetsuTetsu in, but she’s had a hard time being placed with the right person – she's been surrendered back to us three time in the last year – she's had a rough go of it but always ends up seeking out the right people it seems.” Bakugo was drawn in to the three sleeping forms, walking closer until he was just a foot or so away. TetsuTetsu was snuggled into Kirishima’s side, mouth hanging open with the drool of a deep sleep. Kirishima was snoring lightly and had a hand brought up to wrap around the smaller form laying atop him. When his eyes laid on you, a little puppy hybrid with soft ears, tall, little triangles even as you slept, a big fluffy tail and an unnerving amount of old healed scars on the exposed skin he could see. Your face looked so peaceful, lashes shadowing on your cheeks, eyebrows drawn together in your sleep as if your dream bothered you, even a little kick of your leg across Kirishima’s stomach as you shifted in your sleep.

Something in Bakugo reached out from inside of him, his mind or his heart he couldn’t tell the difference – all he knew was that this feeling was one he couldn’t easily shake. He didn’t know if it was because you just looked like you needed protecting, or because the director said you were returned three times and he’s never turned down a challenge, but Bakugo now had his mark set on you – you are who he wanted to know more about, to bring home and keep safe, and he would jump through any hoops to make that happen.
