We see a man coming out of the shadows, the blood moon reflecting it's light on him. He goes up to a cliff, he's eyes red as the blood, holding a katana black as the midnight, the dragon on the tsuba of the katana. The guy was named yami the darkness holder, yami: I am coming for you baku. Now the scene shifts to baku and sayaka where they were enjoying themselves eating ice cream, holding hands, they were unaware of the danger coming to kill them.
Baku:Hina having fun.
