Seina Yamada has a lot of luck... all bad! In fact, Seina has so much bad luck that he has enough to share... and usually does, whatever he wants to or not. Things have been known to break whenever he's around, and he himself has had so many injuries that his family usually struggles with his frequent hospital stays.
