Work Text:
Little Bakugo is so obsessed with Animal Crossing. He doesn't ever touch the game when he isn't regressed, but once his mind slows down and he relaxes into that state of mind, all he wants to do is play his game!
It makes the job of being his caregiver very easy. It is often Izuku that fills that role, and really, all he needs to do is make sure that his Kacchan is nice and comfy on his bed and has his Switch with him.
Izuku also has a Switch, and sometimes Kacchan will whine and beg him to play and they will go collect all the fruit on both of their islands together! Izuku secretly keeps planting more and more fruit trees on his island because he knows how much the blond loves doing that. So the more trees, the longer it takes to gather all of the fruit.
It is just something that the two of them do together to pass the time. Kacchan really enjoys the game, and nothing can stop a tantrum in its tracks faster than placing the boy's gaming device in his hands with the game's loading screen up.
In fact, there had been one time when Izuku had been off campus busy with his work-study and couldn't be there for Kacchan when he wanted to regress. So he went to some of his other caregivers, Kirishima and Sero, to keep an eye on him while he was little. They didn't know the little trick to calm him down.
So when they told him that, no 'Suki, we can't color with you right now we have homework to do, and the tantrum of the century started, the two boys had to just suffer until the green-haired boy got there.
One quick text at the time of Izuku's usual arrival had said boy knocking on Kirishima’s door promptly. He was there for all of two seconds before he went over to Kacchan and picked him up to settle him on his hip — the small-minded boy knowing to wrap his arms and legs around him immediately.
"You wanna play our game, honey?" Izuku coos, easily carrying the blond with one arm and wiping his tears away with the other.
The other two in the room stared back with slack jaws. One, Katsuki never let anyone else pick them up, and two, the way his crying stopped and his face lit up so quickly at the mention of whatever their game is.
"Yes, pwease!" Kacchan grinned, tugging excitedly on Izuku's shirt. "Can we 'Zuzu?"
"Of course, kiddo! I wouldn't have asked if I didn't want to," he answers easily. "Say goodbye to Kiri and Sero first though," Izuku's tone has turned a little stern and he tilts the little towards the two still staring at them.
Kacchan, reminded of the ill feelings he'd felt during his tantrum, buries his face in Izuku's neck and mumbles his goodbyes.
"Nu-uh," Izuku says gently, bouncing the boy on his hip to get him to stop hiding. "Proper goodbyes now."
"Literally how?" Sero asks in disbelief at the same time Kirishima says, "he listens so well to you."
Izuku sends them sympathetic smiles paired with a one-armed shrug (the other arm still occupied with holding Kacchan).
But then a hand unfurls from Izuku's shirt and waves at the other two boys, and then a second later Kacchan was picking his face up to look at both of them. "Goodbyeees... sowry for cryin, I really wan-ned my game..."
Kirishima and Sero nod and smile at him, still having no idea what game they're talking about. They tell him that crying is okay and that sometimes it is difficult to express your emotions while Kacchan just hides in Izuku's neck again.
Izuku, sensing their confusion, promises himself to text their caregiver group chat to explain what Kacchan is talking about once they get back to his room. He nods to both of them and leaves the room then, carrying the little over to the elevator.
Even though Kacchan's bedroom is right next door, Izuku knows both of their Switches are up in his room and he knows little Kacchan likes his place more.
"How are you doing, buddy?" Izuku asks while he switches what hip Kacchan is sitting on.
The elevator dings and the doors open to reveal Todoroki and Iida. The two step to the side to politely give the pair more room. Izuku smiles his thanks to them and steps on.
Kacchan hides more in his neck and Izuku can't help but bring his hand up to tickle at his chin, "hmm, Kacchan?" he prompts.
"I okay now that you got me's," he says honestly, mumbling it into Izuku’s shoulder.
"Awe," they both hear Iida coo softly.
Izuku grins, turning to him, "he is adorable isn't he?"
The three of them all agree and Izuku laughs lovingly at the soft embarrassed whines they all hear.
Their stop comes first and Izuku tells the other two his goodbyes before stepping past the doors. They make it to his dorm without issue after that and he gets Kacchan all tucked into his bed, kissing the blond on his forehead sweetly before stepping away to grab their gaming systems.
"I'm sure we have more fruit to pick if you wanna play together today?" Izuku asks as he plucks one Switch from the dock connected to his TV and the other from its spot on his desk.
When he turns around to hand the blond his device, he sees Kacchan spacing out staring at his own hands. Izuku coming into his line of sight doesn't change a thing.
Izuku understands immediately; it is one of Kacchan's tells when he is coming out of littlespace. He waits patiently for a couple more moments before he calls out the other's name softly, "Kacchan?"
"I'm okay," he says, voice cracking as he talks in his lower register once more.
Izuku smiles, "welcome back, how are you feeling?"
He only blinks for a second more before making eye contact with Izuku for a mere second before looking away. "I'm good, th-thank you for.. that..."
When Kacchan is big, he sometimes has a hard time showing his gratefulness. Izuku still appreciates any attempt he can get. He also knows there are some other questions he has still.
"You wanna come up fully or go back under?" Izuku is careful to keep his tone neutral and caring. He really doesn't mind either option for his friend, knowing that he'll be here for him either way.
Kacchan shrugs and waits a moment, thinking and staring at the Switch in his hands, before flicking his eyes back up to Izuku to gather his reaction. "Go back if you're okay with it?"
Izuku stretches his mouth in a big, proud grin. He comes over to sit on the bed next to him and gives him another forehead kiss (they are secretly Kacchan's favorite). "Of course, little one, you let me know when you are ready to play and I will get my game loaded up. For now, I am going to put away my books, okay?"
He waits until he has Kacchan's nod in agreement before getting up from the bed and dropping the backpack he had brought in with them. He knows that transitioning from his regular head to his little one can be a bit difficult for Kacchan sometimes, so he turns away to give the boy some privacy while he really does busy himself with putting his textbooks away in his desk drawers. They've been doing this for long enough that Izuku knows Kacchan's needs.
It isn't long before he hears, "otay, 'Zuzu! wanna go your island firsts."
Izuku smiles and happily grabs his own gaming console. He loves how simple-minded his little Kacchan can be sometimes.
"Sure thing, buddy, lemme open up my gates."
