Yamanouchi Kagetora is the main character in the GameCube game Odama. He is a general who, in the game, created the Way of Ninten (a reference to Nintendo that means "the way of heavenly duty"). Kendare, Kagetora's sworn enemy, murders Kagetora's father. Kagetora swears revenge on Kendare, though only has an army of thirty soldiers whereas Kendare has an army at a much larger size. With this in mind, Kagetora creates an object that will give him the upper hand. He calls it Odama, a large boulder that can plow through his enemies, though can act as a double edged sword and kill his own soldiers as well if they get in the ball's path.
