I can help you with Bleach. I'm a bit obsessed. xD Ichigo, Rukia, Renji, Orihime, Ishida, and Chad are among the most popular/well-known really. But the other popular ones include Byakuya, Yoruichi, Urahara, Grimmjow, Aizen, Ulquiorra, Hitsugaya, and maybe Matsumoto [just throw HUGE tits on your chibwee with orangey-strawberry-blond hair, and you're pretty much done for her LOL].

I can help you with them if you need to work out distinguishing marks. Like Renji's tattoos, Kenpachi's eyepatch, Byakuya's hair piece etc.
