Kodai Shojotai Dogoon V

A college student named Tsukimiya Shota moves into the house where his archaeologist father, Yuzo, had last been living when he disappeared. Shota inadvertently awakens Doji-chan, a novice yokai hunter, when he finds her breastplate half-buried in the garden of the house. As if juggling his classes with dealing with the clingy and doting Doji-chan were not enough, Shota soon finds that Doji-chan's fellow apprentices, as well as their mentor, have taken up residence in his house as well.
