Chapter 2
They were lead into a station, filled with documents and legal looking arrangements. It seemed less like a child development and safety building and more like a regular office. The entire place was unsettling and was probably even more so for the already wary child.

Aizawa and the workers went into a separate room, leaving the three of them to eat offered snacks and drinks. Momo and the boy ate fiercely, one trying to restore their quirk while the other was simply a starved boy.
After quite some time, Itsuki now fully fed and safe, drifted off into sleep, resting his head against the crook of Momo's neck. The two of them would certainly need a good bathing after all was said and done…

It took a bit, but the adults finally beckoned for them to come in the room. Aizawa had a strange look on his face - almost apprehensive - while the rest of them looked to the heroes in training with hopeful expressions.

"So this is what we've worked out," their teacher started. "How do you two feel about being parents?" He gave one of his signature Totoro smiles.

"Wh-what!?" the two of them erupted.

Itsuki somewhat jostled in his sleep, while Momo willed him to continue resting, feeling somewhat guilty for helping wake the child.

"What about the kid's parents? Where the hell are they?" Katsuki snarled. "You can't just give someone's kid up for adoption!"

"We've had our teams looking into our databases and he just… isn't coming up yet. There aren't any records of him. Until we either find his parents or a different situation, we may have to rely on you," explained the chief.

"I ain't ready to be a dad yet!" Katsuki shouted as Momo clung to Itsuki slightly.
"It's more like a temporary thing," one of the workers corrected. "Aizawa will be his 'legal guardian' while he resides with either one of you until graduation. Then, should you two become pro heroes and make a reasonable enough income and provide a stable living environment, you can be given his custody. Should that be something either of you desired."
"I... feel like that isn't supposed to be how something like this works…"
"Usually, you'd be correct, Miss Yaoyorozu. However this is a special situation, similar to the one of Eri." Momo smiled, recollecting the times with the small girl. She was glad all of that mess was over and the girl was happy and safe. "The boy is about the age she was when she was brought into the UA dorms. Lemillion and Suneater are working on providing her with a stable environment. And they show promise. They look to be adopting her in the next two or so months."
Katsuki scrunched his brow, glowering, and lowering his voice, "Are you saying we're supposed to adopt this kid after we graduate?"
Momo stroked the sleeping child's hair, looking very much his mother. Katsuki felt partially aggravated that she'd already bonded with the boy over such a short period of time, but also couldn't begrudge her as he felt the same. He just knew there was no time to care for an actual child while he was competing to be a number one hero.
"That... seems like a tough situation," Momo commented. "We're both still children ourselves... we'll still be naive and new to the world once we graduate. Is it wise to leave either of us in charge of this boy?"
The man scratched his beard, his age becoming apparent. He rolled his shoulders and regarded the two teenagers carefully.
"You're absolutely correct, once again, Miss Yaoyorozu. You're both much too young to be guardians of any child, nonetheless this one. But, somehow, within these short past few hours... he's gotten attached. He's imprinted on the two of you, and any disruption of that imprint might prove to be catastrophic. This child has a powerful quirk. We're not quite sure what it is yet," he informed them, seeing their confused expressions. "However, it's definitely something we'll have to be keeping an eye on and researching."

"Many adults might be blinded by all of that that," a different worker chimed in. "Either that or he'd be a target and most parents wouldn't be able to deal with villains coming after their child. You two are powerful and are living in the dorms of UA. One of the safest places to be. Not only will the boy be with you frequently, under your personal attention, but he'll also be under UA's security surrounded by veteran pro heroes. Does this not sound like the safest and least traumatizing option for the boy?"
Katsuki growled, "I'm not trying to be a dad, jackass. I'm going to be the number one hero. Being a teen dad is..." he ran a hand through his scruffy hair. "It's not an option. Have someone else do it."
Momo glanced at him, knowing Katsuki was softer than he let on. She considered the boy in her lap and felt a pang of sadness at the thought of being separated.
"I'll do it."
"Yaoyorozu!?"
"He's so young and he... doesn't trust anyone. We can teach him to trust people again and once that happens we can discuss possible options. Besides, he needs somewhere to stay and someone to care for him while he goes through his testing and background searches. Might as well be with the only ones he seems to trust."

"He'll get over it!"

"I don't want him to have to though."
"Don't be so damn emotional, Yaoyorozu!" Katsuki snapped. "You're the number 2 at UA right now, you know that right!? This kid will just drag down our studies-"
"Bakugou. I'm well aware of my standing, thank you very much. Itsuki is not a baby. He won't disturb my sleep nor will he 'drag me down'. And, should that ever occur I will discuss with him how things are going to work. I'm not... throwing away my career to take in this child. Nor am I throwing out this child to promote my career. Both can be achieved with the proper time management skills."
"... You're fucking crazy. You're leaving the second and third spots to me and that lukewarm bastard, you know that?"
She narrowed her eyes at him, suddenly gone was the motherly warmth. "You really think I'd just lay down and surrender my title? You're out of your mind Bakugou Katsuki. Do whatever you'd like, but I'll help care for this child and maintain myself how I will. With or without your help."
He felt a chill jolt down his spine on the intensity of Momo's glare. She was a frightening adversary indeed. His shoulders sagged in defeat, before grumbling, "Yeah sure… do whatever the hell you want. Just leave me out of it."

And that was how they returned to campus. Aizawa dropped them off in front of the dorms, explaining that he'd brief them in the morning on how things would proceed. The two young adults found themselves entirely thankful that it was a weekend.

Itsuki clung to Momo's skirt, having woken up a little, as the trio walked into 3A's dorm building. Due to how late it was, most of their classmates were in their rooms asleep. Momo and Katsuki felt the strain on their own bodies and they longed to do the same. The lobby was scarce, save for Midoriya, Iida, and Ochako.
The three of them, most likely in the middle of a late night study session, based on all the open books and flashcards - and color coded highlighters on Iida's part - looked up at their sudden arrival. They smiled in greeting before looking confused.
"Welcome home guys..." Midoriya started. "Who's... your friend?"
Itsuki rubbed his eyes and hid behind Momo.
"This is Itsuki," Momo introduced. "He's going to be staying in the dorms with us for a little while."
"What!?"
"He imprinted on Ponytail and won't leave her alone. Cops guilted her into taking the brat until they can figure something out."
She frowned at him, but kept silent, simply giving itsuki's small hand a squeeze.
"Mama..." Itsuki whimpered, suddenly feeling uneases by being at the center of attention. He was already somewhat fussy due to the long day he'd had.
Katsuki glanced down at the kid. "It's Momo, kid. Not mama. Don't get too attached."
Momo got down on the little boys level. "Itsuki, it's alright. They're my good friends and they're heroes too, just like us. Okay?" She smiled, trying to reassure him.
It seemed to work as Itsuki smiled shyly in return, appearing a bit more relaxed.
"Okay, mama."
"Kid, listen-"
"I don't mind if you want to call me mama, itsuki."
"Wha-!?"
"Really? It's okay?"
"Of course. This isn't about me. I want you to feel safe and comfortable and you're allowed to tell me if something makes you feel bad or upset, okay? This is only going to work if we communicate with each other. So I say you're allowed to call me mama, since I'm sure it makes you feel better."
She took the little boy's hand and stood back up.
"We'll be heading to bed," she announced to the others. "I'll explain everything properly in the morning. But it's been a long day and the three of us are tuckered out."
"Wait a minute," Katsuki interrupted. "The kids gonna sleep with you? Like in your bed?"
"Unless he doesn't want to."
"Ponytail..."
"Unless you want him to sleep with you, we hardly have any options, Bakugou. Now I've argued with you enough for one day, and I'm exhausted. Let's all go to sleep and work everything out in the morning."

Momo picked Itsuki up, making her way towards the bathing area, more than ready to get herself and the boy cleaned off and ready for bed.

Katsuki glowered at the other three side characters before trudging up the stairs to the boy's side of the dorms, already knowing it was going to be hard to sleep that night.
