The Saginomiya Clan are specialized demon exterminators. It is said that Isumi has the strongest power from successive generations but why did she lose it? According to Isumi's mom, to regain lost power, it solidifies when one turns 16 but having a feminine appearance, being born unlucky as a butler, and being initially named "Ha" which is limited to a boy are necessary. Sure enough, is she already 16?? 
Why does Isumi-san go out alone when she knows she'll just get lost all the time?
¿Por qué Isumi-san no deja de salir sola

Por que a Isumi-san sai sozinha se ela
