Simple cause Amoi lived around the warring era and lived in kirigakure which was the time the Jizou Clan was forced to move in the back of the village, Reppū lived in her house most of the time and apparently wasn't aware of the clan that was in the village thus running to the outskirts of the land of water and keiji lived in iwa before defecting so here's how they end up in yomi academy.

They all were kidnapped by unknown Yokai beast and was teleported to the academy.
