Sukami Kyouichi and his older sister Hanaichi come from a long line of exorcists. Both are accustomed to fighting ghouls, ghosts, and monsters, but when Kyouichi angers an actual god, it’s Hanaichi who pays the price and mysteriously goes missing. While searching for her, Kyouichi meets Chloe Kowloon, a grim reaper who claims to be Hanaichi’s friend. Chloe promises to tell Kyouichi anything she knows if he will help Chloe retrieve her lost memories. But the only way to do this is to complete the “Ghost Diary”–a notebook belonging to Hanaichi with knowledge on defeating any supernatural being. Can Kyouichi and Chloe finish the diary, or will its subject matter finish them first…?
While staying at a creepy seaside hotel with the Occult Club, Kyouichi finds out about Chloe’s questionable approach to completing the Ghost Diary. They butt heads and he decides he no longer needs her help – that the Ghost Diary will be completed by him alone! But with a man-eating mermaid on the loose, breaking up the team could spell disaster.
A vengeful monster is out to get the Sukami family! The Occult Club is on the hunt, but they have to be extra-careful, because making eye contact with the monster is a one-way trip to insanity. Meanwhile, emotional turmoil is stirring up all sorts of trouble. First, a lovestruck Chloe quits working on the Ghost Diary and then she disappears, meaning Kyouichi’s got two missing people to find now. It’s the final volume of the paranormal drama, and the stakes have never been higher–or creepier. Will Kyouichi ever find his sister? FINAL VOLUME
