However, Rishia devotion and love to save him grants her the power of a Vassal Wielder through Itsuki's own Bow and defeats him, much to his shock.

Aultcray Melromarc XXXII
Even though the reason for their status as fallen noble was because of Aultcray's actions, Rishia and her family still believe that Melromarc will remain peaceful, as long as Aultcray was there.
