I didn't like the ending of the anime and guess that Saito only marrying Louis is set in stone so my desire is this. Saito gets summoned by Louis and becomes a familiar, only he is smarter, more ambitious, and has a way to counter Halkegenian Magic from Nobles and Elve and enslave them. There might be brutality, but mostly just him getting a Harem. Gore, Sex, Parody, and story
