Dark Gathering, Vol. 3 by Kenichi Kondō

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.

It’s official—Keitaro and his childhood friend Eiko are an item! Unfortunately, there isn’t much time to celebrate their new relationship status as Yayoi sets her sights on a new spirit and Keitaro takes on a new pupil—an accident-prone high schooler with her own haunting secret.
