you made 4 mistakes theses are all stated in the novel

mistake 1 Ingvald is unstable so she cant be used just yet

mistake 2 the power Penetrate rendered Rizevim Sacred Gear Canceller usless near the end of there first fight

mistake 3 the power Penetrate rendered Diehauser Belial power Worthlessness  useless to durning the city of Agreas fight

mistake 4 is when Issea used D∞D for the first time rendered Rizevim Sacred Gear Canceller usless without Penetrate

there is no way Diehauser Belial power Worthlessness is going to be of any use to him if they end up fighting

but the Pseudo-Dragon Deification limits are still unknown so there is no telling what effects Worthlessness will have
