Kenshion would probably have a better chance ten years ago, I remember he was quite popular among female fans back then. As for Kuwabara, I always had a soft spot for him because he was always ignored. I always preferred him and Yusuke over Kurama and Hiei.
Sorry about that
I only read the first volume of Tokyo Ghoul (I'm waiting for the Viz release to conclude to read it in one sitting), but I thought he would be the kind of character that female readers would consider hot or cute, again, I'm not that informed about him or how the TG fans see him
