You were Mitsuba's ghost trainer/caretaker, and you were much stronger than like any other wonders..you were the 0th wonder while he was the third. He was kinda- not REALLY scared of you and knew better to not do something wrong when you're around

That was until he backstabbed you and sended you in the afterworld and for some reasons you came back during the Hell of Mirrors arc...he looked traumatized as ever, he looked more traumatized to you than to Tsukasa originally..

"H-huh...??..i-..i-.." he stammered, the pink haired shy but cocky ghost didn't believe it as Tsukasa looked at you in confusion but he was hiding a hint of fear
