shinano tokimitsu

Tokimitsu shares many similarities with Ai, as both of their aura codes initially appear undefined. It is later revealed that Tokimitsu possesses the gravity, or "dark" aura. After discovering his aura code, Tokimitsu adopts the name Gyurazo. He has the ability to extract aura energy from other aura carriers, sometimes causing their immediate death and leaving their bodies desiccated like mummies. Tokimitsu is a special project of the Aura Development Center. He was taken from his older sister, Nene, who serves as a priestess at a local shrine. However, his cooperation with the A.D.C. is solely motivated by his desire to improve his sister's deteriorating health. In a tragic twist, Tokimitsu learns that his own powers are responsible for his sister's weakened condition. (Source: Wikipedia)
