Santa, the drummer of CLIMB, has just left the band after finding his girlfriend in the arms of a friend. Along with Yuki, the lead guitarist, they start their own band called "Lucifer, The Fallen Angel," and set out to find new band-mates. Recruitment is not easy, however, and on a search to find a vocalist the duo runs across a promising bass guitarist and a local hotel's piano player and singer who has been wowing patrons daily. With little time to spare, can the two round up the talent they desire, or will Sakuya let his anti-social personality hold him, and his newfound band, back?
Lemon Angel used to be a popular band in Japan, until a year ago; at that time, all of the members of the band, except for Miki Suwa, mysteriously disappeared. In the present, Tomo Minaguchi is a first year high school student who was friends with Lemon Angel’s song writer, Yui Kono, before she passed away. When music producer Ryuuta Kogure approaches her to audition for a new Lemon Angel group, Tomo agrees in order to fulfill Yui’s wish. The competition is fierce – will Tomo have what it takes to become the newest member of Lemon Angel?
