Summer is in full swing! Our heroine and her friends — Izumi, Meiko, Akihiro, Kenshi, Tekumi, and Hiroshi — hit the road again. Their destination: the scenic Lake Biwa. But instead of relaxing, the group ends up in a lost place that isn't on any map. No signal. No help in sight. Silence. Fog. And a shadow moving through the trees…
A coincidence — or something sinister? Can they uncover the truth behind this strange place? And what trials of love await them along the way?
