Люпін

Lupin (ルパン, Rupan) was a phantom thief (怪盗, kaitō) in the human world. In the anime, he is shown to have stolen a large bag of pure souls. He was to be defeated by Death the Kid, but due to Patti being a little off in a pose, he managed to escape while Kid berated her, fleeing after some difficulty into the sewer.
