Four Phantom Thieves dancing in the moonlight. Will they steal a jewel, or—your heart?
Four demons possessing inhuman powers race through this world as phantom thieves. They snatch their prey with brilliant techniques, and not a single soul knows their true identities. They never let a target escape, leaving only illusions for their pursuers. On the nights they appear, black feathers flutter, and only the moon smiles silently.
