S02E66: Beauty and the Deceased

Lupin tries to take it easy while Zenigata's away, but he suddenly finds himself being shot at. It's the coming of Beauty, who has accepted secret shooting orders from ICPO Headquarters. At the site where Lupin meets him for a one-on-one showdown, Lupin is blown away by Beauty's powerful Dum-Dum rounds, but gets away with his life thanks to Jigen's last-second save. When Jigen confronts Beauty to avenge Lupin, Lupin has only one handmade fulminate-of-mercury round for Jigen's gun!
