Ren and run split, should we split there character sections now, or not?

Does Took A Level In Badass really apply? Rito's had some character development, but he's still basically the same generic whiny indecisive Cant Spit It Out Ordinary High School Student harem protagonist with occasional Hot Blooded moments that he always was.
