Renjiro

Renjiro was a shugenja who came to the Shadowlands to conduct experiments. He believed that through a combination of ritual and surgery, he could cure the Taint. His vain efforts resulted in his own affliction and possession by an oni attracted to his invasive methods. Renjiro no Oni was a robed monstrosity of muscle and grey matter seeking Tainted subjects. Its human face offered redemption, but then it turned its head and revealed its demonic visage, which extended a drill-like tongue to suck the brains from its victims.
