Mayuki Hyuga

A twelve year old boy with what seems to be extraordinary problem-solving skills. The police are unable to pull anything out from his background, which seems to be purposely hidden. He has never attended school before and appears to be a genius in all subjects with the exception of physical education. He's the head of the Hyuuga family. It is later revealed that he has the power of Shinchi, a power given to the new head of the Hyuuga family. (Source: Wikipedia)
