Europe. Sakuya and Aine attempt to balance their love and professional lives. Aine's feelings for Sakuya and her ability to write lyrics are tested. The band hires Hitoshi Takayama as a producer to prepare for international fame. At first, Hitoshi thinks Aine is nothing more than an outspoken groupie, with no place on band premises or in Sakuya's life. But as he gets to know her he falls in love, hiding his feelings by pretending to be homosexual. As Hitoshi plans the band's six-month move to England to set the stage for capturing European fans, he attempts to break up both Sakuya and Aine's relationship and another couple, one of the band's guitarists, Atsuro, and his girlfriend Yuuka. Yuki, the band leader, and another guitarist, soon put a stop to this plan, letting Takayama know that band members owe their success to their families and lovers. Kaito Yoshioka, president of a rival label, resents Λucifer's success. He decides to use Aine to break up the band and brutally rapes her in an attempt to break Sakuya. A guilt-ridden Hitoshi finds Aine and takes her to his home to try to comfort her, helping her avoid Sakuya out of shame, self-loathing, and fear of being rejected. When Aine tries to commit suicide that night, Takayama tells Sakuya. Devasted, Sakuya loses his voice along with the desire to sing and leaves the band. Yuki realizes that the only way to protect the entire band is to sign with Sakuya's half-brother Ralph's label, taking the band international. Meanwhile, Sakuya tries to kill Yoshioka, but Ralph stops him. He reminds Sakuya that Aine needs him to be with her, not in prison. Ralph avenges Aine by having Yoshioka investigated for tax evasion and fraud, which destroys his company. Aine is in a near-catatonic state, and Sakuya takes her into hiding to care for her. When she again attempts suicide, he cuts his own wrist telling her he will die with her if that is what she really wants. Aine snaps out of her depression and begins to heal emotionally, even confronting and threatening Yoshioka to never bother Aucifer ever again. Takayama finds Sakuya, and with Yuki makes several attempts to persuade Sakuya to return to the band. Aine realizes that Sakuya is avoiding music and is afraid that she will be hurt again because of him. She convinces him to return to the world
