It has been a month since London was struck with tragedy, and a ceremony symbolizing peace and restoration will soon be held. In light of these events, Arsène Lupin plans to throw a party for Cardia Beckford to honor the fulfillment of her wish. Lupin sets out on a search for the perfect gift to offer her; however, he finds himself caught up in the theft of a valuable jewel, and he is framed and believed to be the culprit. With Lupin locked behind bars, his friends work along with Cardia and an unexpected ally to clear Lupin's name and find the real perpetrators behind the heist.

Cardia, a young woman who harbors a deadly poison in her entire body, has lived her life confined in a mansion alone, feared by others as a monster.

Lupin and his companions have been using the mansion of a noble named Saint-Germain as their hideout. When Cardia meets Saint, he makes a comment that seems to carry a deeper, hidden meaning.

A thief known as the "phantom thief under the moon" has been appearing all over London, going after treasures of vampire households and nothing else.

Cardia wants to help, so each of the others gives her training in their respective areas of expertise, and they set out to capture the "phantom thief under the moon" as a finishing touch...
