Nike is the hero of the show. Nike's father had always wished to be a hero, but due to the lack of any great evil to fight against he had to give his dream up. Still, he made his son undergo hard training as a child in hopes that one day a great evil would arise and Nike could fight it. Because of this Nike is a competent, although cowardly, fighter, however like Kukuri he is initially immature and inexperienced. Nike is from Jimuna Mura (which translates to Plain Old Town). Initially Nike does not want to be a hero, but his parents end up forcing him to.
