Nachi

Riki-Oh's younger brother. When they were children, they played hide and seek in the forest. Riki-Oh was found and adopted by the Saiga family, leaving Nachi behind. Because of this, Nachi has a deep resentment towards his brother. Riki-Oh feels immense guilt for the abandonment of his brother, and hopes that Nachi will forgive him

Nachi has psychic abilities, and is able to communicate with people via telepathy. He can also heal wounds and disabilities, which has earned him the nickname of "The Living God".

In contrast to Riki-Oh, who has a Star of David on his right hand, Nachi has a swastika. A disaster is said to occur if the two were to collide...
