i definitely do!! (thanks for asking i really need to develop izumo more oop)
he grew up in a relatively normal family. he was an only kid, his dad worked as a medic, and his mom was a tokubetsu jonin. shortly after izumo graduated to chunin, his father passed away, and his mother retired to civilian life. izumo still keeps in touch with her. (he’s totally a momma’s boy lbr)
izumo didn’t really have a lot of friends as a kid, but he didn’t really want any, so he was okay with it. it wasn’t until he met kotetsu that he really had a real friend. he was pretty average all around: he got good grades, listened to his parents, reached chunin on his second try. he was a good kid.
