Denki Kaminari is an age regressor, why? He'd rather not talk about it.
Takeaway he is, it's a part of him, he's regressed since middle school it's now his second year of high school.
Thing is, whenever he's told someone they either didn't know or they were weirded out, he dropped the rude ones immediately. So now he's in high school and he regresses by himself, the thing is they're still in dorms. He cant just go to the kitchen for a snack while regressed anymore. He cant watch cartoons in a big TV because the common room always has at least one person in it. He cant walk around in his onesies, or with his pacifiers. It's frustrating to say the least.He did consider telling the Bakusquad they're all super cool, they would probably understand, mutual trauma and all that. He just isn't sure, he really likes them and if they left him he wouldn't know what to do. He could go join the Dekusquad but then the bakusquad could just tell them and eventually the whole class would know. sigh He still regresses but it's not as fun when he cant do anything, stuck in one room to regress in, and he cant even have his gear just out because the squad comes in and Aizawa does room checks.
ugghhh
He's gonna bite the bullet. Who should he tell first? Or maybe rip the bandaid off and tell them all at once, he'll do that, ok he can do it. He'll do it at lunch today, it's a Saturday so he can get them alone not a crowded lunchroom or something. Yeah this will work. He's nervous but...excited? If it goes well he can regress and at least come to their rooms or something, play games with them. That would be awesome.

At lunch Denki is procrastinating telling them, he isn't sure how, they would probably ask why, or other questions he doesn't want to answer. God he should tell them now just do it bandaid right. As he goes to open his mouth he hears it.
"Oi, I got something to say." Welp there goes that, he can wait a little, contemplate how to word it while Bakugo talks."Whats up boomboy?" that makes Bakugo swipe at Sero, Sero, and the rest of the squad, are used to it so he dodges it easily. "Yeah cmon what's up? Something wrong?" ah Mina, the only girl here and she definitely took on the mom friend role very quickly, if they didn't have Mina it would go to Sero but you didn't hear that from Denki. Kirishima doesn't say anything so that confuses Denki.
Bakugo rolls his eyes and slouches in his seat, "Know how they told me to go to therapy." at that the squad quiets, paying rapt attention, therapy means serious conversation especially if it's from Bakugo."Doc said I do some, thing, called age regression or whatever. Said I should tell people im close to, and I spend enough time with you idiots I figured I could start there." and Denki, is in shock. Bakugo regresses too? He doesn't say anything, just watches the squads reactions. Kirishima still doesn't look too invested so that's interesting, did he already know? Or does he just not care? They are dating so he probably knew, that would make sense. Mina and Sero look confused, and Denki hopes his face isn't as obvious, he's confused but for a much different reason.
"Whats age regression dude?" and Bakugo groans, "Basically I have issues, things goin on in my head, so my head goes lets go back to a time when you werent getting kidnapped or getting the shit beat out of you. So I go back to being a kid." The squad looks, totally fine with it?
"Baku baby!" he hears the tch Bakugo makes, Mina ignores it "It's helping you feel better?"at that she gets a nod and now Denki notices a really soft pink on Bakugo's cheeks. Denki is nervous again, yeah Bakugo told them but telling and seeing are different, so maybe if he can see how they react around baby Bakugo then he can really decide if telling will impact their friendship or not.

It's going, good and bad. Good because the squad isn't treating him differently. Bad because, they are clearly not ready for a baby, Bakugo is fairly similar to Denki while regressed, Denki's quirk makes him more hyperactive than others, so seeing them like this taking care of Bakugo, he can't tell them. Kirishima is Bakugo's caregiver, hence why he wasn't phased, he looks exhausted and hasn't spent much time with Bakugo because of school, and when he does he usually falls asleep. While he's studying if Bakugo regresses it's up to the squad to occupy him, Mina is struggling, Bakugo keeps trying to explode all of the pink stuff in her dorm, and once she had to chase him because he remembered he could use his quirk to fly, Sero had to come and use his tape, they don't get an apology, Sero says they'll work on that later.
