Lured by huliganships

Summary: Izuku had always been fascinated by the sea. When he was still a child his mother told him that her mother had been a mermaid who had fallen in love with a human. Because of that the sea favored their family. Izuku had never understood what his mother meant by that, not until he had grown up and discovered his gift.

Whenever he sang, the sea listened.

The Mating Grounds by huliganships

Summary: The mating grounds were a sacred place. The old songs that all mer children listened to while growing up told them of its location, about the peace that prevailed there, and how it was the last safe haven for every wanderer. Lure singing had become rare over the years, but most pods still had one or two elders who were teaching the gift to the younger generation.

While Katsuki was sure he would never need to travel there, he hadn't been prepared for how it made him feel watching Izuku swim away from him to find a partner elsewhere.

Find the feeding grounds by ContraryBee

Summary: Izuku is so hungry. The season is ready to change but he's unprepared. He's alone. He's wandering.

And Katsuki is the god's favorite: of course a beautiful, delicious, near-heat bearer would enter his territory, swim right into his hands. He's hungry too. Fucking starving.

Unwanted Gift by TigerLilies64

Summary: Prince Katsuki has been gifted with a merperson of all things. He's incensed that he would be offered such an inhuman gift, but rejecting it would threaten fragile diplomatic relations. So now he's got a chatty merman in his room that he never asked for. What is he to do?

His Freedom and His Fortune by s_the_queen

Summary: "He didn't say his name," she said, casting her eyes down. "He… he said you were friends. That he was looking for you. I made a mistake—" she broke off, a distressed cry at the back of her throat. Katsuki didn't care. His heart was racing. "I told him you made berth here to treat with another mermaid—a siren who fancied himself in love with you."

"Describe him," he spat. "Or I'll make it my mission to end your pathetic life."

She looked up at him, eyes sad. He didn't fucking care. "He had white hair and his face was weathered. He had unusual jewelry—a chain of clasped hands around his neck. His voice sounded like dry sand."

She needn't say more. He knew exactly who had his love.

Izuku was in the clutches of his greatest enemy—the pirate Shigaraki—the White Hand of the Sea.

-or-

Izuku, the siren who holds Katsuki's heart, has been kidnapped. Katsuki will do anything to get him back.

got something for your BakuDeku heart.

i call this one Our silence it takes place after the exams when they were fighting All might

The hospital room was quiet after Recovery Girl left him, Midoriya has already been to this very nurses room more times than he could count. The only thing missing is the sound of the machines monitoring his vital signs that normally filled vacant air.

She said his back was horrible and she was barely able to heal it.. He knew All Might had to go all out during the exam; earlier he was even wearing weighted gear but it didn’t slow him down at all! Still, Midoriya thinks back to how his back felt when All Might messed it up, he could barely move! Only hopping on adrenaline until he saw Kacchan in his idol's hand. His body moved on its own again he couldn’t just make it without him. He closed his eyes and sighed.

Holding his friend’s unconscious body as he ran towards the escape gate. Kacchan would have never allowed it if he were awake. He’d want to make it on his own. He looked over at the blond who was sleeping in a recovery bed beside him.

“I’m sorry I had to do that to you and ruin your pride..” He uttered quietly in his mind. 

He laid there in the sunset lit hospital bed until he felt like he could move a little better. He sat on his bed wide awake wincing when he felt his bruised side easily with his hand. He glanced over at Kacchan, who was still asleep. Recovery Girl did him justice, made him look like he had only survived the trial with mer scratches.

He sure looked peaceful.

She said he would be out for a while so he wasn’t expecting him to get up anytime soon. However a few moments passed and he saw him begin to stir. His eyes fluttered open and he squinted in the dim light of the room.

"Kacchan," Deku said softly, risking a disturbance in their rare silence. 

This time it was different; he didn't snap or yell. Instead, he looked right at him with a strange vulnerability in his eyes that took Midoriya off his guard as any look Kacchan tended to throw his way good or bad..

Slowly, as if fighting through immense pain, He semi-rose from his bed since their beds were so close together he didn’t really have to get up to go wherever he was going, (which just so happened to be towards Midoriya) He made his way over and the silent room fell into even more silence as he approached closer. An intense expression fixed on his scruffy face dared him to run away but that's not what he was saying, he wanted him to stay still.

No words, only large relaxed sharp red eyes staring into Midoriya’s green.

He blinked, unable to comprehend what is happening as Bakugo stills in front of him. And then, before he could even get a word, thought, voice or sound out, Kacchan leans in, plants thee softest (and only) kiss on his lips.

Midoriya’s eyes widened in shock and surprise as their lips touch more. Slide more. Open more. He doesn’t touch him no, that would ruin it (but would it really?) his hands stay albeit awkwardly shaken beside his person on the bed. Bakugo is doing everything while Midoriya is just trying not to melt away.

Unknowingly he keeps pulling back trying to back up into a wall but there is no wall and if he backs up anymore he’s going to fall backwards out of the bed. Everytime he moves Bakugo uses that moment to drink him in moving his head like he’s done this before but he knows he hasn’t.

The jerk’s been single his whole middle school but he’s still better at this somehow.

When they pull apart for air he says “Kacchan” not knowing if it’s a question or what, maybe wants him to do something? He’s already doing enough so why did he say his name? He doesn’t remember when he realizes the weight of the other boy on his lap. He’s straddling him and he feels like he’s going to fall over. “Kacchan..” He says again really wanting to put his hands on his body but he doesn’t know if he can.

Is such a privilege allowed?

At a point he opened his eyes closed them and open them again, he went back to try and continue the kiss however as quickly as it started it was over. Kacchan doesn’t give him an answer either; he just pulls away slowly with a slight wince from the pain it had caused him to move.

In this moment they just stared at each other; Midoriya trying to process what had just occurred while Kacchan looked at him with another expression he didn't recognize behind those fiery eyes.

"Nerd...I didn’t need your damn help," Kacchan mumbled before breaking eye connect making his way back to his own bed. “We’re even now, don’t expect me to do anything like what you did during that exam.. ”

Saving him? Was this a thank you?

Midoriya remained seated on his bed - trying to make sense of it all - unable to move or even do that while the room returned to its previous silence. Maybe not the same but a silence that was similar.

This was written to be super sweet i hope you like it

i love you so bad for this already

I WISH YOU COULD SEE MY FACE RIGHT NOW IM SO HAPPY I LOVE THESE TWO SO MUCH GODKJSDKJLODF

This was so sweet, it's so them, such a conflicted moment, neither of them fully understanding their emotions and not knowing where things will go from here... i love this

i have no words just woah, thank you for sending me this, it really made me smile so much

[monstermashzine]

i only found out about this zine today, and was interested in applying as an artist at first, but asking for 3 different concrete (and mandatory) pitches on its own is already a tall order for a zine i haven't even been accepted to yet, and having to supply sketches on top of it is even worse! a detailed summary seems like a lot to ask up front for writers, too... i vibe with this zine's mission, but that's just too many requirements for a mere application. i hope you'll consider this feedback for next year.

Henlo! O u O///

I'm sorry to hear of your feelings on our application process, but I hope this will help clear some of your concerns.

Our application process doesn't ask for concrete pitches or sketches. As far as I've been able to gather, it's customary for zines to ask for pitches during the application process. I don't have a lot of experience when it comes to participating in zines, so I spend a lot of time looking into the application of other zines and conferring with my mods about the best procedures for us.

It may seem like a matter of schemantics, but we don't ask for sketches, we ask for concept thumbnails. From my understanding, a single thumbnails should take no more than a few minutes to create, and is designed to be a very rough draft of a sketch. It usually focuses solely on the main focus point, and is often subject to extensive changes throughout the production process.

While my wording was initially misleading during the first edition, back in 2022, I've since been corrected by a very patient applicant, and the wording has been justly rectified in this year's application requirements.

We ask for thumbnails, not sketches.

Adding to that, when pressed on the issue of whether this was a bothersome or unreasonable requirement during an anonymous performance survey, our contributors had no qualms with this aspect of our application process. This being said, we'll revisit this issue with our future contributors once the project is over, and will work on making changes from that.

As for our authors' application, we've actually lowered our requirements from last year's applications. Where we previously required a 500 word blurb for each of our authors' pitches, we now ask for a detailed description.

When asking for a description, we're asking for anything from a summarized run-down of the intended piece, an intended pairing (FF werewolf/human; Mer!BakuDeku; etc), character descriptions, fandoms, or any other information which may help paint a picture for us.

I've looked into a large number of writing anthologies, and our requirements are quite lenient in comparison.

This may help understand our expectations a little better:

At the end of the day, how much you give us is entirely up to you. It isn't mandatory to provide thumbnails or detailed descriptions. We have applicants who've ignored our requirements before, and it was of no real issue to us.

The reason for our extensive requirements is deeply tied to this project's missions, however, and allows us to select through a wide variety of stories and characters. The MonsterMASH! zine strives to bring people together, and create a product in which stories and art actively coexist. Our application's requirements allow us to meet our project's mission of showcasing a wide array of stories.

It helps us sort through applicants who may have pitches which are a little too similar to another's, and choose which creator would be better suited for our project. This process has worked wonderfully for us so far, and was met with fairly positive feedback.

You're under no obligations to provide us with anymore information than you're willing to offer us. We will consider your application regardless. However, other applicants who do meet our requirements will likely score higher than you, and we'll be made to consider their application before yours.

On a different note, I'd hate to leave any aspiring applicant to feel disappointed. My mods are very busy, and I feel it unfair to ask any impromptu work out of them when they're not paid to help me. However, I think it shouldn't be too much additional work on us to offer you some additional time to work on your application!

If you'd like a few extra days to turn in an app, feel free to reach out to us via email (zinemonstermash@gmail.com), and we'll see to it that you get a bit of an extension.

Thank you so much for reaching out, anon!

Summary: Mina convinces Katsuki to help two humans trapped in their sinking boat in the middle of the storm. Katsuki, for all his claims of disliking humans, seems to find one human rather pretty.

whirlpool by pinchingzuku

Summary: He still didn’t know how he, a mer, ended up being friendly with a human of all things. It still made his brain spin and his fins flicker in annoyance, maybe less than he would have liked, but still.

And definitely didn't expect to see him again, and again, and again.

The sound of the waves by Ana_Writes

Summary: Love is beautiful, everyone knows that. Everyone sees it differently. For some it's the feeling, for others it's the person.

For Izuku? For Izuku it's the sound of the waves.

Being in love with a merman isn't normal or easy but Izuku knows he'll do anything to see Katsuki's face, feel his scales on his skin and hear the soft hum of the waves.

tides by kindaopps

Summary: A new lease of life, then, for this poor boy. 

A whim, nothing more. Katsuki’s good deed of the day. It’d be a waste, to let the life he’d saved slip away in a blink of an eye. 

Katsuki ignores the treacherous voice inside him that tells him that his whim had something to do with the dream-like, nebulous future that Katsuki saw in glimpses.

Sharks and ocean predators by @silverynight

Summary: He's ready to dive in, when he sees a very weird black and dark orange fin, it looks like a shark's. He knows sharks are not usually aggressive, but he doesn't want to upset it, so he decides to stay on the boat for a while, hoping it doesn't see anything interesting and decides to go away.

However, the shark doesn't go, instead it bumps into Izuku's small boat a couple of times until the green haired boy falls into the water.

Izuku closes his mouth and opens his eyes to see the creature and realizes that's not a shark but a merman; he's never seen one like him before. Uraraka's fin is completely different from his; from the waist down he looks like a black shark and the rest of him looks like a blond boy with red eyes, sharp teeth and well built body.

{One Shot}

mer-made in heaven by Fangirl_on_fire

Summary: Over the next few weeks, Izuku kept returning to the cove. He brought a few gifts for Katsuki—slices of dried kelp, a pretty shell, things he had figured out mermaids often liked from his studies at the laboratory—but Katsuki never reacted beyond a slightly interested lift of his eyebrows. Still, Izuku was lucky just to have the attention of the most gorgeous person he had ever seen, mer or human.

As if it weren’t enough that Katsuki was devastatingly handsome, he was cute, too, with the way he scrunched his nose up when the sunlight hit his eyes or he idly splashed his tail in the water.

Tidal Wave by LoonyLoomy

Summary: When a young Izuku goes to the beach one day to find a boy with a lionfish tail, he's immediately enchanted. Katsuki is the coolest friend: confident, talented and bursting with amazing stories about life underwater. Little do the boys realise, however, that a mistake can change everything in the blink of an eye.

Oh yeah! The fic for this AU is now complete!!

[Note: I did lock my fics, so yes you do need an account to read them.]

MER!MIRUKO & MER!DEKU

════ 🌊 ════ 🌊 ════

Alright, it's Mermay, and now I got thoughts! I love mermaids and anyone who knows me knows Miruko and Midoriya are my faves.

So of course, this post is going to be all that combined!

First! Shoutout to my lovely moot, @minisheku

I have had so much motivation to conjure up some details of this Mer!AU have in mind now that my eyes have been opened!!

THANK YOU SO MUCH, MY FRIEND!! 😭💜

I also ask to be patient with me here since I cannot draw, so I'm working with words here.

════ 🌊 ════ 🌊 ════

Mer!Miruko

For Miruko, she's a sea bunny mermaid to me. So like in canon, she does have a Rabbit tail and ears. Except, the features are more aquatic. The ears are white and tipped black, thin like a sea bunny's rhinophores and her sea bunny tail is black instead of the white in canon. Her eyes are red, just like in canon. Her hair also remains white, like in canon, but also switches into purple at the ends.

The base color of her mermaid tail is white with black, purple, red and gold scales scattered on it here and there. The same scales cover her sides and breasts. In addition, she has black fins, a larger one on the end and two side fins, one on each side of her mermaid tail. She has deep brown skin.

She has gills on the sides of her neck and her "rabbit" tail works as gills. Miruko's hands are also clawed (like how Burnin's hands are) and she has a black coloring that runs from her hands and up to her forearms like gloves. Miruko also has fangs, her default, however when she gets aggressive or defending herself, all her teeth are sharp (think Kirishima). Her build is how she is in canon athletic and curvaceous. She also has a thin scar on her left arm from an incident.

Like sea bunnies, Miruko's diet consists mostly of algae, seagrass, and sea sponges. However, she doesn't shy away from eating other sea life. She also has eaten humans.

Due to her diet, Miruko possesses toxins that she can use to paralyze and potentially kill however she chooses. Her rhinophores/ears works as sensors to detect chemicals.

Miruko's personality is relatively the same as in canon. Bit abrasive, speaks her mind, a tough cookie. Here though, she's also friendly, caring and protective. She's wary around others, except Izuku, Inko and Hisashi. She has instincts that alert her of potential threats and has ease reading others.

════ 🌊 ════ 🌊 ════

MER!DEKU

At first, like Miruko, I envisioned Izuku to be a sea bunny merman, but changed him to a sea sheep merman. (Idea was inspired by my lovely moot.) As he does in canon, he still has his green eyes, green hair with black shadows and freckles. Instead of human ears, he has sheep-like ears that droop down. Of course, aquatic and thin, and the ears/rhinophores are sensitive. They're colored green.

The base color of his mermaid tail is black with green, light green and teal green scales scattered here and there. The same scales cover his sides and stop just under his chest. His end fin is spiky, a bundle of green cerata (the leaf-like appendages) resembling the body of a sea sheep's. He has smaller cerata in a bundle at the base of his waist to form a sheep-like tail. He also has these same green appendages going down his back.

Like Miruko, Izuku has gills on the sides of his neck. He also has fangs, that can convert to rows of sharp teeth whenever he feels aggressive and defensive. He has clawed hands. From his hands up to his forearms is a light green coloring that blends into his light skin. He also has freckles on his shoulders, and many scars as he does in canon, the most prominent one being the large abrasion on his upper right. His fingers on his right hand are also slightly deformed. He also has defines muscles.

Like sea sheep, Izuku's diet relies on algae. Also due to possessing chlorophyll in his cerata, Izuku also can perform photosynthesis. He also eats smaller aquatic life, seaweed and humans.

His rhinophores/ears work as sensors. He also has the ability to create "smokescreens" that are more effective underwater to blind his targets and work to hide him.

Again, like Miruko, his personality is nearly the same. He's compassionate and often times excited about learning the world around him and easily analyzes what surrounds him. He used to be timid, but over time grew out of it. He's also protective (mostly of his family) and sweet as he is, Izuku is prone to get angry and violent.

════ 🌊 ════ 🌊 ════

Here's some added details!

There are other merfolk and it's not often male merfolk are born, so Izuku is a rare case.

As in some tales, merfolk are violent in nature, responsible for some disasters and tragedies. However, not all merfolks are like this. Some are peaceful and only choose to become aggressive whenever they're in danger.

They're capable of magic, often using it to create homes and children. Sometimes, merfolk use magic to grant themselves han appearances. Miruko and Izuku can do this.

Jumping off that, when children are born, they are first enclosed in shells that don't open until ready. The infants are typically the size of a tennis ball at birth.

For a little bit of history, Inko and Hisashi were newlyweds when they found Miruko and Izuku's shells and raised them as their own children at a house near the beach inherited by Hisashi. Inko and Hisashi are human.

For now, that's all I have for Miruko and Izuku are merfolk! I'm still working on more for this AU, not planning on making it too big of one though and I do have a fic in the works for this AU.

For now, do feel free to ask questions!

A Sea of Green and Red ch. 19 (A BakuDeku Mermaid Au)

Chapter 19: Solid Ground

Gone were the days of happiness and fun. There was a big battle to prepare for. One that they would very well lose if they weren't careful and didn't trust one another.

There was only two humans on their team but even they they needed all of the mer kingdom to trust them in this battle.

As promised Katsuki had spoken with the king with Kirishima. At first it hadn't gone anywhere but over time they eventually called a truce. They both agreed that the fate of the merpeople was far more important than Katsuki bedding the prince's intended.

But they would speak of it after apparently.

As promised the word was sent out to the kingdom. Those that wished for safety would go to the deep sea caves to hide until word was sent that it was safe. They were upset about leaving their homes but they knew that the caves were much safer.

To Katsuki's surprisedthere were many mermen and mermaids that actually wanted to stay and fight. Most of them were the guards of the kingdom but there were others that weren't that were ready to make a stand against the humans for their home.

The guards showed Katsuki and Kirishima, as well as those who weren't well versesd in the ways of battle, how to fight underwater more fluidly. It was a little more difficult for the humans but they found a basis of what to do and manipulated it to work in their favor.

The water was their grand advantage. If they got them into the water it would make things easier to fight them off.

But that was more than likely where the battle would not be taking place. Katsuki knew his crew and he knew that they did everything they could to not end up in the water whenever there was an altercaton to be had.

That's where his knowledge came in. With Iuzku teaching how to grow their legs, for those that had no idea how, and Katsuki with teaching them human battle techniques. He always warned them to never leave themselves open, to always make sure they were protected.

This crew would fight dirty.

On a suggestion they used kelp leave to press over their mouths. Mina had suggested that even if their kiss was gone they would need to use these to protect themslves just in case one of them was grabbed and forced to kiss.

If anyting they were more than read tof ight. At least that's what Katsuki hoped for. With how Izuku described Shigaraki before he had left he was sure the man was unhinged after not getting what it was he wanted.

At dawn they were ready. They were near the island and the ship was getting close. The merfolk were under the water, waiting.

Their main goal was to bring them in an area where they would have an advantage. In order to do that they would need to take down the ship.

With enough force they could take the ship down.

It hurt Katsuki to think that they would need to take down the ship that was one his home. He had been there when the ship had been first gotten. He had helped take care of it and took pride in it whenever they sailed away with a win.

Now it was just a bitter reminder of his old life and the people that he used to be around. It wasn't as great as he had once thought it was.

“Ready?” Kirishima asked next to him. Katsuki clutched the sword that he had been given. It had seen better days being under water for so long but it was all they had that wasn't made of stone.

“Ready as I'll ever be,” Katsuki said with a scowl, double checking his fire arm. He honestly couldn't wait to see Shigaraki's face when he realized that he was still alive.

And that Kirishima and himself were there to fight for the merfolk.

Izuku popped his head out of the water and swam closer to shore. Despite Katsuki urging him to go to the sea caves with his mother he had refused to go despite being pregnant. He wanted to fight. He wanted to protect his home.

He wanted to see Shigaraki's reign stopped.

“Kacchan!” Izuku called out as he tugged the kelp away from his face. Katsuki waded into the water, resting his hands on his arms.

“Izu, what are you doing? We're about to go into battle,” Katsuki said, worriedly looking at the fast approaching ship.

“I wanted to give you a kiss for good luck,” Izuku said. Katsuki rose a brow. He knew something but he trusted him.

“By all means then,” he said, gently cupping his cheek and guided their lips together in a gentle kiss once more.

Izuku knew. Oh he knew. He knew very well what was happening.

He remembred what they said about them following him. No doubt the captain had his eyes on the forbidden prize. So Izuku was showing him just what he wanted him to see. Giving his kiss once more to the man who deserved it, who was very much alive.

The two of them pulled back slowly and Izuku leaned in to whisper into his ear.

“When this is all over...I want to celebreate privately with you,” he said into his ear. Katsuki felt his skin get warm and he wrapped his arms around his merman.

“You little...” he said with a soft laugh. “You know how to get a man all hot and bothered before a battle hm?”

“You know I do,” Izuku said, leaning back to cup his face. “Just promise me you'll come back to me. That you'll stay safe.”

There was worry in his green eyes. Now that Izuku had shown Katsuki and Kirishima were alive no doubt they would be targets. It was clear on Katsuki's face that he knew.

“I promise,” he said, kissing his palm and then gently pulled the kelp back up onto Izuku's beautiful lips. “You as well.”

Izuku chirped at that in his sign of a promise and then sank back into the water.

Katsuki smirked, heading back to dry land, Kirishima patting his shoulder as they laughed.

*

Shigaraki's hands shook as he stared through his telescope. There was his merman, poking his head out of the water.

And then there was the bane of his existance kissing on him as if he hadn't been on death's door not just weeks prior.

He snapped his telescope shut, storming his way towards the crew that had scattered to the edges of the docks, fearful of his rage.

“You told me he was dead!” Shigaraki roared at them. “I took his life with my own eyes. You left him there to rot!”

“That is what we we said sir,” said one unforunate crew member that ended up getting a shot to the stomach. He doubled over in pain, crumpling to the ground.

“Then someone tell me why he is on the beach with his redheaded nuisance kissing on my merman yet again!” Shigaraki roared.

The crew remained silent, not wanting to witness or experience the same fate as their dying fellow crew member.

Shigaraki threw his telescope onto the deck much like a child. It shattered to pieces and the crew still remained silent.

“Someone bring me his head,” he declared. “And make sure that the merman watches it happen. I want him dead.”

“Yes captain,” they all chimed in.

“And my merman. Bring him to me. By force,” Shigaraki sneered.

At first things had been silent. None of the underwater army spoke as the waited for the first strike. And when it came things were quick to action. They dodged bullets and canon balls aimed into the water as fast as they could, swimming to the surface with their spears and arrows and fired away up at them on the ship.

Most they missed at the odd angle the fired but some were luckier than others as well as the firing squad on the beach.

But it wasn't enough. It was becoming hard to dodge and who knew how much arsenal they had gathered at the cove.

Katsuki had been afraid of other crews coming with them but from the looks of it they all thought he was insane back at the cove. They wanted nothing to do with him. Too much trouble to go after one mermaid that may, or may not exist.

Mermaids had been a myth to them that ended up being real. But most pirates didn't bother with myths unless they were truly bored or insane.

Shigaraki had defnitely been insane.

“We need to get up there,” Izuku said, looking up at the ship. “Who's with me?” Several merfolk agreed with Izuku, including Shoto, and a few others that looked to be octopi. Izuku remembred hearing that they had come after helping Shoto.

“To the surface,” Izuku called, leading the group to the surface. Their heads poked out of the water and with some concentration they emerged with their legs. One by one they grabbed hold of the ship, using whatever they could to climb aboard with their weapons in hands.

The pirates were not expecting this at all as they were soon surrounded by merfolk walkng on legs just like them.

“Don't let them ksis you,” Izuku said around his kelp mask as they all agreed and went in for the fight of their lives.

Izuku swung his sword gracefully, dodging attacks like he had been doing this for years. He hadn't but Katsuki was a great teacher.

There was one pirate that he was aiming for and that was the captain. After everything he had put him through Iuzku wanted to be the one to take him down.

“There you are,” growled Shigaraki's voice. Izuku turned around, his eyes hardening as he readied his sword. “Didn't even need to be brought in. You winllingly came on your own. Now be a good little fish and get in your tank. Then we can call this whole thing off.”

He was lying. Of course he was lying. They had other mermen and women that he had the pick of the litte from.

“Never on your life,” Izuku said muffled behind his mask but Shigraki scowled nontheless and pointed his sword at him.

“Then perish.”

Katsuki let off another shot from his gun and cursed as nothing came of it.

“We're too far now,” Katsuki growled, picking up his telescope and his eyes widened to see what was going on the ship.

“What's going on?” Kirishiam asked.

Katsuki cursed and gathered up his things, heading towards the boat that the two of them had scrounged up.

“Come on, they got themselves onto the ship. And Izuku is leading the charge,” Katsuki said, not patiently waiting as Kirishima stumbled into the boat and Katsuki started to row.

“Why is he even up there?!” Kirishima asked in panic. “He's pregnant.”

“I don't know, but I'm going to put an end to this once and for all.”
