Mitsuki and Yuuya have just become step-siblings, and are working to adjust to their new lives as a family living within the same house. While Mitsuki is cautious of this new relationship with her ‘older brother’, her inhibitions quickly take a turn for the perverted when she’s suddenly possessed by Hiyori, a ghost girl with amnesia.
