In Happy Town, a place where humans can revel in their lust and desires, Momo has been kidnapped, so Ten and the fireworks craftsman Goemon raid the central tower in order to rescue her. On the topmost floor, the battle against Klown kicks off! Thanks to Goemon's efforts, Klown is down for the count... Or so it seems! He's only cast aside his disguise to reveal his true, hideous nature, bringing destruction upon the town. With Goemon too wounded to go on, Ten steps in with his pitch-black rosary. When Klown asks Ten if he's enjoying himself now, how will Ten respond?
