Gokudou Yuccot Kikansky

Unlike most main characters, he is closer to a villain than a hero. He doesn't hesitate to abuse the needs of people, sell out his friends to save himself, run away from any dangers, or ditch others who helped him if he doesn't have any more interest in them. His life starts to change when he finds a magical Genie named Djinn who will to grant him three wishes. As most people would benefit from having three wishes, in his case it leads him to a lot of trouble, and it doesn't take long before he tries to escape from Djinn, as well as every other person he meets.
