Elsie is glad to meet her friend Haqua, a genius who was one of the best students in their class and is now the Section Chief of District 32 of the Far East Division. When Elsie ask Haqua how many spirits she has captured, Haqua claims she captured ten and is in disbelief at first when Elsie says she captured five as she always known her as a klutz. But their conversation is interrupted when Elsie's boss, Chief Docrow, reports an evil spirit is on the loose in her area due to a failure of another spirit hunter. Haqua decides to capture this spirit by herself but Keima, after hearing her talk with Elsie and seeing her suspicious attitude, tells Haqua that he knows the spirit hunter who let the spirit loose was Haqua herself as she was chasing it before she meet Elsie and Docrow reported it. While Keima isn't interested on why Haqua is keeping it a secret from Elsie, he offers to help her find the spirit at school in exchange for telling him what the evil spirits are. Haqua explains the spirits are the souls of the Old Demons of Hell who were overthrown and sealed by like-minded Demons who were oppose with the former's wicked ways but managed to escapes to Earth and hide in girls hearts which the spirit hunters are tasked to capture them before they are reincarnated as their host's child. Since the spirit feeds on negative emotions, Keima leads Haqua to the most depressing place in campus, the school theater. Keima decides to leave everything to Haqua but she needs his help and admits to him that she hasn't caught a spirit yet and lied to Elsie to save face. Is then when Elsie reports to her that she has found the spirit in the theater.
