U-1

U-1 (ユウイチ), also known by his alter-ego Gitaroo-man (ギタルマン) is the main protagonist and player character of Koei's PS2 rhythm game Gitaroo Man and it's PSP port Gitaroo Man Lives. He is voiced by Yuka Imai in the Japanese version and Lenne Hardt in the English version.

U-1 comes from a normal white collar family and is an elementary school student. He is a clumsy Average Joe who is considered to be a loser by his rich classmate Kazuya and is constantly bullied him. He admires his classmate Pico, and tries to do anything to get her to like him, even by saying he's an awesome skateboarder with a strict training program even though he's not. He also pulls stupid stunts not related to skateboarding to convince her, but is ultimately put down by Kazuya.

What U-1 does not know that he learns from his talking dog sidekick Puma, is that he inherited the blood of the legendary Gitaroo Man and wields the legendary Gitaroo, a guitar type weapon that shoots lightning as it plays and changes U-1 into a soldier of Planet Gitaroo.
