The Ancient Dogoo Girls (2010)

In the sequel, a college student named Shouta Tsuikimiya moves into the house where his archaeologist father, Yuzo, had last been living when he disappeared. Shouta inadvertently awakens Doji-chan, a novice youkai 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, Shouta soon finds that Doji-chan's fellow apprentices, as well as their mentor (Dogu-chan from the previous series), have taken up residence in his house as well.
