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?? 
Yes. But even if she did it for me, she brought this on herself, so please forget about it.
Sí. Pero aunque fuera por mí, ella 
se buscó esto, así que olvídalo.
Sim, mas mesmo ela tendo feito isso
por mim, ela sempre pega para ela.
