Shadow Joker

A phantom thief and one of Joker's rivals. Blinded by hate, Shadow doesn't think twice before attacking anyone that stands in his way. His spontaneity as well as his unpredictability is what makes him dangerous, and he'd rather blow everything up than using actual strategy.

Shadow fights with a black umbrella called Bloody Rain that shoots laser beams. Its flying function also allows him to escape from his enemies by flying away from the scene.

He joined Professor Clover's organization in order to revive his sister, Rose, after she fell into a coma, exhausting all her power to protect him when their village was attacked. His devotion to Rose, whether it be for the good or evil, reverberates on his actions a lot. He would sacrifice anything for Rose. Because he and Rose had met Joker (then known as Jack, an apprentice phantom thief) prior to the attack on his village, his hatred of Joker stemmed from that meeting, as they had switched places, leading him to believe that if they hadn't, he would have been able to protect Rose.

After Rose was freed from Professor Clover, he and Rose serves as allies to Joker and his friends, even helping them to outwit Devil's Fang. Even though he still holds the same, fierce rivalry with Joker, if the situation calls for it, he would team up with Joker to get out of a difficult situation.
