Miko, who abandons her ascetic training to become a convent nun to instead assume the singing dreams of her twin brother’, Mio, by replacing him as a member of the hugely popular rock band, A.N. JELL. The band’s leader, Ren, though overflowing with musical talent, is also an extreme neat freak and perfectionist who keeps others at a distance and refuses to recognize Miko or anybody else’s talent. The band’s other members consist of Shu, who seems to have a little more of a forgiving personality, but is actually just extremely detached. Yuuki, while on the surface a complete airhead, keeps balance in the band, particularly between Ren and Shu. Miko leaves the communal life of a nunnery to join that of a rock band, but will she be able to “gel” with A.N.JELL? And bringing a girl into an all-boy band is sure to produce some interesting chemical reactions; perhaps even some chemistry between Miko and Ren, not to mention a fair share of jealousy, tears, camaraderie and even a search for parental love.
