Ito was recognised as a genius early on and was brought up 2 years in school. His older brother used to pick on him due to being jealous and so did other kids in his school. His family was pretty poor so they his brother was forced to quit school and get a job. However no matter how much he asked to help his parents wouldn't let him 'throw away his talent' and he felt guilty for this. He blurts out facts randomly sometimes and he seems to secretly enjoy reading yaoi. He couldn't say boo to a ghost and knows he's weak, but thinks that he might be able to help with his knowledge and says he'll do whatever he can.
