One day, Toshio approaches the Kisugi sisters with a highly unusual request for help. He is taking part in an operation to expose a businessman named Iwao Yagami, who has hired a hitman to kill Cat's Eye after they have stolen too many pieces of his precious art collection, and gone into drug trafficking to finance his revenge plan. Toshio intends to win Yagami's trust by disguising himself as the hitman, who shares a startling likeness with him, and pretending to kill Cat's Eye - and therefore, he wants Hitomi, Rui and Ai to effectively pose as themselves!
