The 4-koma crack comedy is back, and this time around Gorou's crush on his sadistic, older stepsister Haru has reached the stage where more or less openly sexual innuendos have become part of their everyday life.The pair's "peaceful" days would have continued if only it weren't for Haru's cousin Aoi-chan and (dangerously?) younger sister-like existence.
