Kami nomi zo Shiru Sekai II EP5 - FLAG 5.0 It Always Rains at the End of a Hard Journey

After learning there are still 60,000 spirits to be captured before his contract is finish, Keima goes into a depression, not helping matters when his classmate the cheerful Chihiro Kosaka makes fun of him. Despite telling Elsie he doesn't care what people say about him, he is still affected by Chihiro's words. Suddenly, Elsie detects a spirit and to Keima's horror, it's inside Chihiro. Keima refuses to help her since he's still angry on what she said and the fact she's very average and doesn't have any unique traits that can help him figure her out. However, they watch her confessing to a boy, only to see her get rejected and runaway crying. The next day, Keima, feeling sorry for Chihiro, decides to console her over her rejection but to his anger, Chihiro is back to her old self as she reveals she has been confessing and getting rejected to any boy she fancies many times. Keima scolds Chihiro for playing around with love but she strikes back with his obsession with games and his anti-social attitude which strikes a deep cord within him. Even more depressed, Keima locks himself in his room for days until he does come back to school but refusing to speak with anyone. Worried about him, Ayumi visits Keima who has fainted from not eating.
