Hoichi Kano

The main character of the series, Hoichi's life is turned upside down when the Riofaldians take over the Earth by force. Hoichi is called "Gun" by his friends, which is a joke on his name. He is called this due to the fact that the kanji symbol for Ho in his name means "gun" in Japanese. On the day of the tenth anniversary of first contact with the Riofaldians, Hoichi meets Isaka, a beautiful, not to mention well-stacked, young high school girl who claims to be dating Hoichi. She turns out to be a creation of Hosuke Kano, and gives Hoichi the Gunner Suit Glove, which allows Hoichi to change his clothes into a power suit. After fighting off Riofaldian robots, Hoichi is taken to the XXX Unit, Exaxxion. (Wikipedia - http://en.wikipedia.org/wiki/Cannon_God_Exaxxion)
