Move in with your wife and son, because a hero caught your tail and you don't want to leave them alone?” Yoichi muttered, ignoring the nod he received as his brain was still trying to process the words he just heard.

Summary
What do a tired Albino trying to keep his feral sister in check, said feral sister, and a green bean with Anxiety have in common? For one, a lot of child support from the Boogeyman of the Underworld.
When Izuku Midoriya accepted One for All, he wasn't expecting it to come with seven passengers as his personal cheerleaders, and he definately wasn't expecting to attract the attention of a girl with multiple quirks and no concept of person space.
When Ayame Shiramoto applied for U.A's hero program, all she was expecting was to see some new quirks and pick them up. She definately was not expecting to get a family bigger than her brother.
When Yuu Shiramoto finally decided to chill out and stop babying his sister, he was not expected to get dragged into a world of Heroes and Villans, or have to face the man that has haunted his nightmares for over a decade.

Summary
“The best place to be is right under your enemy’s nose.”
Yoichi’s eyes hardened. “You really shouldn’t have told me that. If I am a traitor, then I would have just revealed the heart of your organization.”
“We shook the trackers off of you. The one in your hand was deactivated when one of my men zapped you, as you know. The meta-ability based ones can’t track you if your destination is Shojiken’s target. If you leave, you forget the specifics and will only have a vague notion on how to get back.”
Kudou let himself grin, showing all of his teeth.
“And we will never let you leave, anyway.”
Yoichi’s eyes narrowed, and he smiled back with just as many teeth.
“Good. I don’t intend on leaving.”

Summary
Yoichi told the boys in great detail all about how cool vigilantes are and were while he and the other adults were looking for the remaining resurrected legacy heroes - so Izuku just doesn't get why his uncle seems so determined to stymie his and Kacchan's patrols. It's completely unfair!
Oh, well. At least they're still allowed to go out and play after school - and meet some new friends along the way. Maybe if they were to do something heroic but small and manageable, like toppling an extremist organization while they're on summer break, they can prove to the adults that they're responsible and have the sense to stick to safe-ish missions...
