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?? 
I see! It'd make sense if she thinks she's got it together if this is what her family is like.
Ya veo. Tiene sentido que piense que es 
mejor, teniendo una familia como esta.
Entendi! Tendo uma família como essa, é 
fácil achar que melhorou mentalmente.
