// Gitaroo Man(2001)

The player character is U-1, a young boy who is frequently ridiculed by classmates and passed over by Little Pico, the girl of his dreams. The story proper begins when Puma, a dog with the ability to speak, teaches U-1 to play the guitar, simultaneously teaching the controls of the game to the player, and subsequently revealing to him that he is the last legendary hero of Planet Gitaroo, and the possessor of the Last Gitaroo. When they are then attacked, Puma transforms into Puma AC-30 and gives U-1 the Gitaroo, transforming him into Gitaroo Man.
