As daughter of the former demon lord, Mio's foster parents were slain by powerful demons after her life. Still seeking to slay her, Basara reveals himself as a member of the hero clan--an enemy of the demons--and vows to protect Mio as a member of his family.
But earlier you said that the 
hero clan was watching us...

dass der Heldenclan uns beobachtet.

Pero hace un momento has dicho que el clan 
de los héroes nos estaba vigilando...

 ci teneva d'occhio...
Mas antes você disse que o clã dos
 heróis estava nos observando...
Но ведь клан героев до сих пор считал 
нас просто целью наблюдения.
