STAR Transfer Student (Izukuxyn)

It's 2030, you've lived your whole life in Spain, now you're starting hero school, but your parents, having their roots in Japan, have you transfer into a prestigious Japanese school for a year, your life there is definitely out of the ordinary and then you go back home, being a different person, maybe now home isn't a house anymore, maybe the meaning of home has changed... Turned into a person.

Or; you go to UA for a while, fall in love, come back, go back to end the war, and stay for the rest of time.
