Dark Gathering, Vol. 4 by Kenichi Kondo

[Viz] 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. The encounter with Ai’s ghastly groom may have devastated Yayoi’s defenses, but it also triggered the birth of a terrifyingly powerful new spirit. With this “graduate” in hand, Yayoi unveils her plan to capture the god. The only question is whether Keitaro can handle a whirlwind tour of Japan’s deadliest haunted sites.
