Voiced by: Fujiko Takimoto (1994-1996), Omi Minami (2000), Shizuka Ishigami (2017)^[8]

Nike (pronounced Nee-kay) is the protagonist. Because of this, Nike is a competent but cowardly fighter. Like Kukuri, he is initially immature and inexperienced. Nike is from Jimina Mura, (which translates to Plain Old Village). Initially, Nike wants to be a Wizard as he finds the thought of casting a fireball "cool", though his parents convince him to be the Hero. He initially thinks that he is of the Hero class, as do others. It is later revealed that he is a Thief. Despite this, he can use all the abilities of the Hero class, including Gallant Pose, which only a Hero can do.

Bado (バド)

Voiced by: Hiroshi Masuoka (1994-96)

Bado is Nike's father. He had always wished to be a Hero, but due to the lack of any great evil to fight against, he had to give up on his dream. However, 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. He received a critical hit in the form of a punch the first time he held the infant Nike. After that, he trained Nike to be a Hero. Right before he departs for Kodai Castle, Nike offers him his old helmet. The helmet is cracked, but Nike suggests he will wear it by tilting it to the side. Bado kicks Nike into the air and keeps the helmet on, saying that he looks like a gang leader.
