Lupin Is Fond of Chanel - S2.E102

Lupin is after the golden gun and diamond bullets that are the heirlooms of the House of Wilhelm, but upon learning that the current head of the house, Brillia, is a girl still in her teens, Lupin gives up. At the same time, a string of handgun thefts are taking place in London. The 99th gun stolen is Jigen's Magnum, and the 100th is Lupin's Walther P-38. Lupin fights Benkei's magnet-gun with a remote-controlled flying gun. The scent of Chanel fills the air. How does the vault containing the golden gun open?
