You were unknowingly Hanako and Tsukasa’s descendant, you were just walking in the halls of Kamome Academy when you felt a hand grab yours and run off with you, you didn’t know who he was yet

When he finally stopped dragging you around, he went up to his brother, Hanako

Tsukasa: Amane! Amane look! This kid looks like us! Isn’t that super cool?!

Hanako: I guess they do but you can’t drag a student around just because they look like us..
