Rockers (2003)

Guitarist Ko-chan is a mess of sexual repression after a childhood at the mercy of two elder sisters eager to use him as a guinea pig for their make-up skills. Bassist Gaku-chan keeps a bucket in the wings for whenever his nerves get the better of him, and drummer Momo-chan is doomed to forever carrying the botched childhood attempts at self-tattooing. It's not until this foursome is forced to look for an additional guitar player after Jin's dad burns his Stratocaster, that attitude and musical ability enter into the equation. Leather-clad, shade-wearing Tani (Tamaki), inseparable from his black Les Paul, is introduced as the king of R'n'R cool and Jinnai keeps him firmly seated on his throne throughout the film, retroactively proclaiming the guitarist, rather than himself, as the band's true hero.
