Berlin - RY X

As much as you wanted to do as you were told and take good care of yourself, you couldn't bring yourself to do it. Sure, you were tired like your father, but there was a reason. Nightmares. Being diagnosed with PTSD because of rape and parental abuse really took a toll on your body. One lousy day ended with you being taken to the hospital for fainting. 

Bakugou made it clear that Kazu was in good hands, and despite only knowing the guy for about a week now, you counted on the angry blonde. So, you sat in your room doing things other than getting rid of your dark circles. You just sat on the floor, leaning against your bed and staying there without moving. All you had in your hand was your phone scrolling through social media until a message appeared on top of your screen. 

[??????]: 

Stop leaving me on read Y/n! 

Craning a brow, another message appears after the other. 

[??????]: 

Please let me make it right between us!

The messages are one of the many messages you ignored. After you block one account, a new one appears to take its place. At this point, you wondered if you should just delete social media altogether and find something better to do during your free time. Blocking the accounting again, you switched your phone off and threw it over your shoulder. It bounced on your bed, leaving you one less thing to worry about. 

"Bathroom," You sighed. Picking yourself off the floor, you walked into your bathroom. The sink is what you need, specifically the cold water faucet. You splashed water on your face and did it again since you missed most of your face the first time. Beside your sink, you kept a small towel for Kazu. Instead, you used it for your face. 

Looking all over, you groaned, seeing clutter all over the counter. "My room is such a mess," 

"So, kid, what are we gonna do today?" Asked Bakugou sitting Kazu on his shoulders, earning raspberries in return. Walking in on Bakugou talking with the little infant, Midoriya greets his childhood friend, and others begin to flood the common room with noise. Then the girls start to notice the infant patting down Bakugou's hair. The one who eventually stole him off of bakugou's head was Mina.

"Good morning Kazu-chan~" She greeted, repeatedly bouncing the boy in her arms. 

Bakugou raised a hand as soon as he turned. "Oi- be careful he just-" 

He was cut off by the sound of vomiting. Mina gasped when Kazu vomited all over her shirt. Bakugou slaps himself on the forehead. "-ate," 

"Here you go, Bakugou, you hold the baby," Mina gagged, handing the baby back to Bakugou. The boys dropped to the floor, laughing at the pink girl striding into the baths.

Bakugou brought him close to his chest when he started to cry. "hey, it's okay, kid-"

Bakugou inspects Kazu's clothing, sighing in relief, seeing as there was no vomit on his all might onesie. Patting Kazu's back, Bakugou managed to silence his cries telling him it was okay and he was alright. In return, Kazu let out giggles as he clung to the collar of Bakugou's top, which made Bakugou smile.

"Hey, bakugou's smiling!" Kirishima yells. 

"Quiet shitty hair!" Bakugou barks at the redhead, who only sparked more laughter in the room. Joining everyone else were the remaining students of class 2-A. That's when Bakugou sat Kazu on the floor. Before the accident, the girls following behind Mina greeted the infant, eating his own hand. 

Momo was in awe, and in her hand, she created a stuffed toy in the shape of a dragon for Kazu, large enough for the little boy to cradle in his own arms. It made him smile; his gummies flashed at the girl's starry-eyed gazes, making them gasp. 

"Hey, Momo! Do you think he likes other animals too?" Asked Ochaco while Momo created several matryoshka dolls from her palms. 

"I'm not sure, Ochaco." The raven-haired girl said with a shrug. Her creations amazed Kazu; he grasped a couple of dolls and chewed on the heads. This forced another gasp to escape, this time from Denki. His mistake of poking Kazu's cheek led to him getting bit. 

"Ow! Guys, we got a bitter!" The blonde screamed dramatically, grasping his finger, earning a loud laugh from Kazu.  

"You idiots! he gonna choke on the matryoshka dolls! Keep a better eye on him." Bakugou scolds them, snatching the baby off the floor and moving him away. Momo is quick on her feet at collecting the dolls she made. 

"To the matryoshka box, they go," Momo sighed, carrying the dolls away. Shaking his head, Bakugou held his hips as he glared away from his classmates. In his hands, Kazu still clung to the dragon plushie. 

Kazu pulled the plushies wings before biting down on the dragon's head. Ochaco's lips formed a pout, deciding it was time for breakfast. However, she had an idea and used her quirk to make the baby float with the plushie. Unknowing to her, Kazuko started hovering too quickly and missed her hands, attempting to catch him. Denki and Sero watched everything whilst Bakugou talked to Kirishima. "Uh oh,"

"You're acting like his mom," Stated Kirishima, making Bakugou click his tongue. "Speaking of his mom, where is she?" 

"She looked tired and needed a break. I offered to watch over the kid so she could rest," Bakugou explained, remembering your tired expression. 

"That so nice of you, man." The redhead slaps a hand on Bakugou's shoulder. "Need a little help? I love kids," 

"Knock it off, Kirishima," Bakugou barked, moving towards the couches. "And, of course, I need help. He's our teacher's grandson, goddamn it. You little shits are helping me no matter what,"

"M'Kay! Looks like looking after Kazu will be a breeze if we all work together," Said Kirishima sending Bakugou a toothy grin. Bakugou is reluctant since most of them are the only child in their family, himself included. 

"I doubt it. You guys don't have any siblings, only frog face and icy-hot and-Where's the baby?" His own words interrupted his sentence once he noticed the missing child. Ochaco, Sero and Denki look at Bakugou, sweating nervously. Izuku and Shouto enter the room through the elevator. When no one answered his question, Ochaco pointed up to the roof, causing the ash blonde to look up. He sees Kazuko stuck to the ceiling, chewing on the dragon toy.

"What the fuck? H-how did he get up there!" Bakugou yelled, pointing up at Kazu. Ochaco shamelessly raised her hand, gesturing to her fingerpads. Bakugou's fingers twitched, fighting the urge to choke the life out of her. "One job...you had one fucking job, and you blew it,"

"Don't worry, bro! We'll get him down," Sero promised, lifting his elbow.

"Shoot your tape at that baby, and I will strangle you with it," Bakugou warned him, scanning the area until his eyes landed on Izuku. "Oi Deku,"

"Yeah," The boy answered.

"Use your float quirk and get him down," Bakugou jerks a finger at Kazuko, then Ochaco. "And you! don't release your quirk until that stupid nerd has the kid in his arms."

"Alright, alright,"

Doing as he told, Izuku floats over everyone and moves towards Kazuko. He used his other quirk black whip to get to Kazuko faster and pulled him into his arms. Kazu smiles at the young hero, who smiles back, saying. "Hey there," 

Since Bakugou is the oldest in class A, he's classified as their big brother! therefore, he's the more responsible one out of everyone in this story.
