Takeshi Tsujido

Takeshi is an older man who is trying to track down Matsuri. When fighting her he wields a large sword unaffected by Yaka powers with the intention of killing Matsuri and uses ultraviolet lamps to try to immobilize her. His intention to kill her is due to a promise to turn Mayuko back into a human and if he succeeds then Matsuris sacrifice will restore Mayuko back to normal. Source: Wikipedia
