Coming from a family of thieves, Hana Mikumo is a librarian in the open, however, she gets caught up in a whirlwind of dirty mischiefs due to her skillful abilities as a robber.

Even though the ‘Lupin’ family motto is to only target the villains, Hana’s sweetheart called Kazuma Sakuraba, is always caught up in their thievery, due to his job as an investigator. At times, he is often attacked by some of these villains, and this in turn makes Hana feel the need to save him from them, but these kinds of action lead to unwanted consequences...

The supernatural grudge manifests itself by way of a strange cyst growing in the body of a young woman, slowly draining all life from her in revenge for... what?
