Joker

Past Timeline

With the money earned from magic performances, he went to gambling in a back alley gambling house, and dark gangs started chasing him. However, each time he runs away using illusion magic. He got a bounty and was chased by a bounty hunter, Ruri. However, he seems to enjoy running away from her and playing a mouse and cat game.
