Lupin is scrambling to find a gift for Cardia when he gets dragged into a heist that's way messier than advertised. The OVA trades the main series' melodrama for something lighter, letting you watch him actually work as a thief instead of just being emotionally devastated. It's the show rewarding you for sticking with these characters by giving you the one thing the TV series held back: Lupin doing what he does best, without apology.

A month after tragedy struck London, the city is preparing a ceremony meant to stand for peace and recovery. Arsène Lupin wants to throw a party for Cardia Beckford to celebrate her wish finally coming true, and he goes looking for just the right present. Instead he gets pulled, unwillingly, into the theft of a precious jewel, a crime more intricate than it first looks. Lupin is blamed for it and ends up in a cell. His friends team up with Cardia and a surprising ally to prove his innocence and track down whoever is really behind the robbery. The single OVA episode mixes action, adventure, fantasy and romance.
