Benisato's special ability is to control snakes.. and shed her skin like one. At one point her body is covered with living tatoos of snakes that come off and turn into real snakes. She is Gemma's lover and the devil that discovered who Jubei was (after Tessai left an imprint of Jubei's face in his hand). She also has the ability to possess people and cause them to burst open with snakes (i.e. the old lady chanting the sutra in the desserted temple). She is very taunting about her relationship with Gemma to Yurimaru, which is reason for the "tension" between them.
