Noel gets a tip about an illegal auction having a Lupin Collection piece on display, so he and Umika go undercover with Kogure's checkbook.

Tooma tries helping out a man on the street and gets persuaded to join a martial arts class. Much to his surprise, the assistant teacher of the class is Sakuya!

The Patranger arrive on the scene to discover a Ganglar being attacked by his own comrades. Tsukasa becomes the most trusting and the Ganglar tells her to watch out for Gauche, who has been collecting safes. However, Noel is still very suspicious and has been forbidden from taking the Ganglar's collection piece.

The Lupinranger discover that a Ganglar with five safes cannot have them opened individually. Noel asks Keiichirou for help and the two end up in a duel.

Kairi has been absent more than usual and so Tooma and Umika follow him, but they get sidetracked by a Ganglar that hits them with a spell that makes people worry too much.

Sakuya has been invited to a Christmas party by a young boy and recruits Tooma to cook the meal, but Sakuya and Kairi run into a Ganglar who is making everyone eat salmon instead of chicken for Christmas.
