While walking through a forest, Santa and the others encounter a demon girl named Sina being raped by a rapewing, a giant bat-like monster. With Pierce "powering up" for a powerful spell with Bobo's help, they defeat the rapewing and Sina tells the crew that her family and friends are being held captive in a nearby cave filled with treasure. The adventure from that point on is a cross between a Dungeons & Dragons-style dungeon crawl and a Scooby-Doo-like haunted house. Santa ties a leash on Pink so she can lead the way (and get attacked first by any monsters). However, it was Santa that walks right into the first trap, taking Pink with him. Pierce & Bobo are attacked by Slave Knights, demonic armored warriors each with an innocent young girl at their core. Bobo & Pierce had no alternative but to kill the girls to end their suffering for being used as the cores for the Slave Knights. Meanwhile, Santa & Pink are captured and molested, respectively, by Nymphomania, The Slave Queen, a naga-esque female. Santa was held over a pit of snakes dangling from a rope. When Pink caught the rope, Nymphomania used a Dildo Cobra to dispose of Pink. Pierce & Bobo came to the rescue at the last second before Pink lost consciousness and Santa began to fall. Seeing Pink severely wounded, Santa became enraged uses a special Sword Dancer technique to obliterate the cowering Nymphomania. After Pink recovered, Santa & Co. rescue the kidnapped girls and find the treasure, but the dungeon collapses and the treasure was buried underneath. After returning Sina to her family, the adventurers wander off.
