History Manga / SouseiNoOnmyouji

** All the children in the Hiinatsuki dorm might have suffered a similar fate, considering [[FridgeHorror they are orphans not only aware of the existence of Impurities, but also feel that the only way they can repay their debt is to become respectable exorcists.]]

Benio's twin brother was among them.]] Besides, Rokuro was also [[spoiler: found in Magano, age around 6, with no memories at all.]]

On a more serious note, both of them have [[{{Tsundere}} similar dispositions]] and have lost loved ones in the past.

* ExtraordinarilyEmpoweredGirl: Mayura actually has a large amount of spiritual powers, but isn't an onmyouji.
