Gitaroo-Man is a quirky Koei game that centers around U-Ichi, a young boy, who is the last surviving guitar man (what about Ralf Machio). Guitar men are heroes who use their instruments as weapons against evil and young U-Ichi is joined by his dog Puma who can transform into a ghetto blaster. The gameplay follows the usual traditions of the rhythm genre and the success of attacks is base on how well the moves match the music.
