Being hated by girls in Japan is really pathetic all around. "She's so annoying." "She only acts with hot guys." "She's not cute." etc etc.
Being on that list, to me, is nothing but good. Sure, maybe it means you don't have many "female fans" but at least they recognize you and acknowledge you and that means you at least are famous.
About hating on Ashida Mana? Seriously? Those people needs a life.
