She appears with the angel invasion pre-timeskip and after that she is seen as one of the seraphs that are fighting against the demons that went to Earth and fought along other angels a much weaker devil, that still was not taking damage from their attacks, cause he was using a device with an angel in it to negate all the spells from the angels, the Void Howling. Said angel was Uriel's sister. After Uriel starts to fall,and Dark Schneider is reduced to a talking head, she starts to fight him and uses her strongest spell Gott Hard that have the power of a supernova, and still don't have effect, but Dark Schneider channeled the power of the attack to regenerate his whole body, after that he does her when she's weak.
