A quiet girl of few words. The crows resting on her shoulders are another story with their blathering personality. Her cuteness invites people to naturally want to protect her but when it comes to games, she becomes the vanguard, spearheading the assault. She might be shy but, at times, she may show her mischievous side to those she gets along with.
