An Arrancar in Highschool DxD!

After their deaths two delinquents were merged together to make a new person and sent to an Anime world called 'Highschool DxD'. There, with the knowledge of one of the delinquents, they will aim to become the King through any means necessary. Oh, did I forget to mention that one of those delinquents was Grimmjow Jaegerjaquez? (Heads-up, the MC isn't gonna have the full-strength of Grimmjow, that'd make him OP in a world like Highschool DxD or at least OP up until a certain point. Instead, he's gonna start at the bottom of the food chain again, and work his way up to the top. Such a thing won't be too hard for someone with Grimmjow's potential. I'm gonna up the power-levels of everyone in the world anyway, just so they're not too pitiful in front of the MC and so they can give him a good fight~)
