Dark Gathering, Volume 7 (Dark Gathering #24-27)

An unwilling magnet for the supernatural and a ghost-hunting little girl join forces to capture Japan's most terrifying and dangerous spirits.

After a dangerous encounter with a malevolent spirit, Keitaro Gentoga wants nothing to do with the supernatural. Unfortunately for this reluctant ghost magnet, he's stuck helping Yayoi Hozuki - a strange young girl who's intent on capturing Japan's most terrifying ghosts and ghouls.

Before they can tackle their next haunted site, Keitaro, Yayoi, and Eiko need to collect another of the sealed Graduates - a vengeful courtesan who's eager to escape Yayoi's control. However, things turn even more dangerous when Keitaro is drawn into the spirit world, forcing him to face the horrors of a haunted love hotel all on his own.
