Yuuna and the Haunted Hot Springs, Vol. 04

Setting spirits to rest is Kogarashi's calling, but the one ghost that he can't quite seem to figure out is Yuuna herself. In between ghostbusting and doing the antics of the hot spring's gorgeous residents, he's done his best to try and figure out just what is that keeps her tired to this world. It's time to take it more seriously... to find out the truth of Yuuna's part! It won't be easy, especially when he gets mixed up with a festive gathering of an all-woman ninja clan!
