Ryuji Nakagi

Kujaku is assigned to retrieve a statue of Ashura, not his partner but one of the ancient Eight Guardians of Buddha, although a connection between young Ashura and her ancient counterpart is eventually revealed. The statue had been stolen from a well-guarded temple by Tatsuma, a student and amateur occultist hoping to use it to awaken his dormant psychic powers and save him years of study with a master.
