The World God Only Knows, Volume 4 (The World God Only Knows #27-36)

Haqua visits Keima's house to fill out a report on the recent capture of spirits. She doesn't remember every aspect of the capture, so she asks Elsie and Keima for help, which leads to a disaster by the end of the day. The next school day, Elsie senses a spirit in Chihiro. Keima is stumped by this event for Chihiro is a mob character, or "the regular of the regular", who has no retaining characteristics. But after some time, Keima sees that even the regular has the necessary characteristics to be captured. After Keima captures the spirit within Chihiro, a new woman comes to Maijima high as a teacher-in-training: Jun Nagase.
