I guess to answer your previous question.
My favorite would be Touma since I can relate to him (after the Kuroi stuff). He has that attitude to always improve himself in everything especially idol talent. I'm kind of like that. I'm always trying to find ways to improve myself because there are people I look up to, and I want them to be proud of me.
Plus, he stopped Kuroi in the anime from further ruining Chihaya's concert. So, I have respect for him for doing deeds like that.
