My favorite character is definitely Ruri Gokou (Kuroneko) from Oreimo. A Gothic Lolita dressed girl that suffers from Chūnibyō. She comes across as egotistical and haughty, but underneath is a shy, intelligent girl that very much cares for her friends. She's also voiced by Kana Hanazawa so that increases the endearing factor
Lol, these peeps never learn
