As punishment for his crimes and for starting the rumbling, Eren Yeager was reincarnated as a genie. He still has his memories about his past life. He doesn't like it being a genie at all....He absolutly hates it. He had done this number for centuries, and he still hates it being ordered around, have to grant wishes against his will....but hey who can't blame him. He must obey if he wants or not. Unlike most Genies who grant their masters 3 wishes....Eren has to grant his Master 5 wishes.
