A long time friend of Morimoto transfers into the school, and along with her, mysterious and bizarre "pranks" start happening almost every night in the grounds. The group decides to investigate these incidents by going to the school at night. They divide into two teams: Shin, Jun and Kanaru, and Takurō and Megumi on the other. With the two older boys overly scared, the girls lead on to find Morimoto's friend collapsed on the floor of the science room. Meanwhile, Jun senses a troubled persona nearby and disappears to the camphor tree on the school's yard, and uses his own to comfort it. (thetvdb.com)
