Yakumo and Haruka investigate the haunting of an apartment rented cheaply by a university student, Date Shota. Through the realtor, they learnt that the previous tenant, Shiobara Kimiko had died of natural causes in the apartment and is now haunting it. Yakumo was able to communicate with her ghost and she requested for a letter (hidden behind the mirror in the room) to be burned. Haruku broke Kimiko's request not to read the content of the letter and saw a photo of Kimiko in it. Despite that, Kimiko was sufficiently pacified and wish Haruka well before her spirit departed.
