I don't know but it's something about Eri that makes her extremely unlikable for me. I mean it's not anything personal. I dislike most kid characters like small kid characters but Eri's just something else. The only thing i really like about her is her design. As far as her design, i don't really like anything else about her at all. I don't think that she's necessarily a bad character, but i don't really enjoy seeing her. But that's just my opinion!
