Suiteiru no Oni

Suiteiru no Oni is a remnant of a villian in a nigthmare lost to time and magic. It was one of the first demons to terrorize Ningen-do, and grew in strength until it became one of Fu Leng's most greatest warriors. It was tasked with destroying a Nezumi city, and Suiteiru no Oni was confident that nothing could stand in it's way. Suiteiru underestimated the power of nezumi name magic, which the nezumi shamans used to erase the name of the city and everything in it. The city was moved into the Realm of Dreams, and Suiteiru was trapped along with it. For over a thousand years they were trapped until 1165 when Tsuno Soultwisters dragged the nezumi city back. A man named Daigotsu Takima informed Suiteiru of what had passed those thousand years, and Suiteiru decided Daigotsu was the rightful heir to Fu Leng. Having vowed to never fail the Dark Kami again, Suiteiru chose to support Daigotsu. In the civil war that tore the Shadowlands apart in the Twelfth century, Suiteiru sided with Daigotsu, unlike many other oni. (CoR3E p. 170)

Appearance
Suiteiru no Oni stands approximately 20 feet tall, covered in a blood red carapace. Only the most sacred nemuranai and purest jade is capable of penetrating his tough hide. Long horns adorn the sides and top of its head, and his hands end in long sharp claws. It wears armor that matches the style of the long lost nezumi empire. Suiteiru is extremely intelligent, more so than most oni, and will loyally follow any who gain his trust. (CoR3E p. 170)
