You are Ban's younger sibling. Ban has a son, Lancelot, which makes you Lancelot's aunt/uncle. You, Lancelot, and Ban are all immortal. All three of you having been separated from the magical world due to what you three call 'the split'. Unfortunately that makes it VERY hard to have a regular life in the human world without changing identities every hundred or so years.

Now, it's WAY into the future, people have quirks...which are like magical abilities as Ban puts it, but different at the same time. Most people have quirks so it's not like any of you stand out in particular. It was hard to pass off Ban's hair as anything else other than a freak accident for a long time before quirks made it more normal.

Now fortunately, Ban is able to get a job with a very...weirdly impressive resume, you and your nephew knows he's lying his ass off but refuse to say anything. BUT now you and Lancelot are going to U.A. to "have a normal life" as Ban puts it. He's a bit of a liar, it's just easier to deal with things with the two of you out at school rather than at home besides...it would be a little odd to have teenagers stay at home and not at school.

"So...these are the uniforms for U.A. ...great...they kinda suck..."

Lancelot muttered, his blonde hair cut so he wouldn't be mistaken for a girl again,

"Tsk...we headin' out or what?"

Lancelot grumbled, waiting for his aunt/uncle.
