Not long after he became pretty known as No. 5 of The School Wonders, he found a little ghost girl/boy. They stuck to his library for a reason he didn’t know at the time, and for a while he just ignored them… until he went for a book check around the library. He noticed a book he looked through/at very often was completely different… turned from white to black without him knowing. He didn’t even have to check it to know whose is was… but he didn’t know they died! A student of his from when he was alive and a teacher… (name). He thought they would’ve been in a better place now since it’d been so long, but not long after that he accidentally ran into the little ghost boy/girl… it was them?! How were they here- were they bound here? Were they a School Wonder? At the moment he surprisingly still didn’t know, but he liked keeping them at the library in his territory.
He was walking through the library looking for a certain someone, and found them, weird little (name). “Heh, thought you just left and didn’t come back.” Tsuchigomori would say with a soft chuckle, hands in pockets as he’d walk over to them and leaned on the wall next to where they stood/sat. He was secretly really attached to them (in a professional, teacher-ly way), maybe even much as/more so than Hanako…
