Suija/Story

Suija is one of Liu Yunfei's disciples from 1,000 years ago who succumbed to the powers of the demon world. He and his brother became powerful elemental demons that were eventually sealed. However, they were able to break the seal. He possesses a shinobi from the Kazama clan, who was investigating evil energies close to the lake where he was sealed. He meant to reunite with his brother and steal a spell that Kuraki-sumeragi possessed. The spell allows demons to better fuse with a human host. With this spell, he wished to possess Sogetsu's body and mate with a woman to spread his essence in the human world. Parallel to Enja's fate with Kazuki, however, Suija is sealed in Sogetsu's weapon by Hazuki.

Due to their likeliness to one another, the dubious nature behind Sogetsu's birth, as well as Suija's need for a human host, several fans speculate that he is actually Sogetsu's father. However, this claim also lacks a solid official source and is generally considered to be conjecture by fans.
