Soshi Seiryoku

Soshi Seiryoku was a shugenja of the Scorpion Clan.

Kidnapped
Seiryoku moved from Shiro no Soshi to Ryoko Owari Toshi to take control of the opium Shosuro cartel. She was kidnapped during her journey, and tortured. Her captors wanted she named an oni, but she knew of the matter and refused.

Seiryoku no Oni
Eventually, they broke her, but Seiryoku had a plan. Without her captor's knowledge she bargained with her spirit promising it her name and more if it would free her. Seiryoku no Oni was born and moved to her house at Ryoko Owari. A tiny second face with an eye, growing on the tip of the Soshi tongue, was the oni's mark on her. The face would became bigger, gaining another eye, and a mouth. When it got all of her, she would be done.

Kolat
Seiryoku was surprised she had not been missed by her servants during the imprisonment. Her most trusted servant approached her and explained why, she had been replaced during this time by a kolat duplicate. Beyond that, her servant exposed her as another kolat who had replaced the true one. The kolat had kidnapped Seiryoku and she woul become their tool, or she would be exposed to the Asako Inquisitors as a shugenja who shared her name with an oni.

Soshi cartel
Seiryoku rebuilt the Soshi opium cartel, and Watchful was her seccond in command. During most of the time he fought to avoid the oni's control, but even suicide was not an option because he would be exposed and the Soshi stained.
