After searching hard for the Papillion Mask, they finally found him-although he was definitely not what they were expecting. He supposedly wanted to bargain with Kazuki: the antidote to the Homunculus attached to Tokiko's body for his Busou Renkin, but Kazuki refused. With a single Kazuki punch, The Papillon Mask was knocked out and brought to be questioned. (The "antidote” was a fake.) As soon as they finished "talking”, the super-powerful Homunculus came to save the Papillion and thus-A NEW BATTLE BEGINS!
