Dark gathering 5.

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.

Having captured the spirit of the H Castle Ruins, Keitaro, Eiko, and Yayoi next set their sights on Tokyo’s infamous Old F Tunnel. But before they can brave their first Danger Rank S location, Yayoi takes them on a detour to collect another one of her Graduates—the ghost of a soldier who, even in death, could not escape the pain of war.
