Ep. 13: Lupin targets a stolen red jewel at a myth-themed auction in New York City.
Aired on January 9, 2022

Bored in New York, Lupin learns of a jewelry auction featuring items linked to classical myths. He spots a large red jewel in the catalog, stolen from his grandfather's vault by a female master thief, and decides to reclaim it. Lupin befriends a florist named Mattea, tricking her into delivering electronic flying drone insects to the auction as part of his scheme. During the event, a heavily armed group of identical red-haired women interrupts, seizing the treasures. Lupin pursues them, but when he stops to save Mattea from falling debris, the red jewel ends up in the leader's hands. As she departs, Lupin reveals to his gang that she knows his connection to Tomoe, the thief who originally stole the jewel and is supposedly his mother.
