Death Note Vol 4 - Love

Light joins L's investigation team, hoping to find the second Kira before them. L asks Light to write a message as if he were Kira, so the second Kira would respond. The second Kira is a popular idol named Misa Amane, who sends instructions for meeting. Light and Officer Touta Matsuda head to the meeting place, where Misa discovers Light is Kira through her shinigami eyes: the eyes are unable to see the lifespan of other Death Notes holders. Misa visits Light at home and tells him she is the second Kira, offering to aid him in his work. Light decides he could make use of her love for him. Later, Misa sees Light talking to L at the university and sees L's real name. Before she could tell Light, she is arrested under suspicion of being the second Kira. Her Shinigami, Rem, convinces her to forfeit her Death Note, and Misa loses her memories concerning the Death Note. In turn, Rem orders Light to save Misa. Light gives Rem his Death Note. L asks for Light to be imprisoned, suggesting the latter may be under Kira's control.
