Miya Koshiro from Yumeiro Patissiere. I'll admit, I used to hate her because of how spoiled she was and how she refused to be nice, but I can't understand how anyone could hate her after she did so much to help Ichigo find the strawberries her deceased grandmother grew! Not to mention how she stood up for Ichigo and Tennouji when Henri started to make fun of them for being in love! She's a great character, and I just Amore her drive to do everything she dreams of doing.
I think in basic opinion,I don't think "everyone" would hate a certain character because it's almost basically impossible to tell what everybody in this word hates o likes for that matter,because we're not them and we can't see their point of view-bah sorry my rambling one character that comes to mind-well is Lizzy from Kuroshitsuji,but I use her all the time,so I'll go with Mikaru-chan from Mermaid Melody. I view her as lonely and just wanting someone to have around which is the reason behind what she did to Kaito-kun..I feel bad for her than anything nothing hurts più than being alone-I'm sure if she had a friend o two she wouldn't have done what did to Kaito..and Lucia..I mean I don't think she's all that bad-she's only lonely.
Kikyo from InuYasha I don't understand why people hate her if I thought my boyfriend killed me I would do the same thing she did also she had a hard life being a young woman and having to protect the sacred jewel from evil and not being able to do fun things
