Late one afternoon, a guy enters a certain room on his own accord. Before him quietly stands the female teacher Miyuki Kageyama… The glow of the setting sun streams through the windows, bathing the room a crimson red. Miyuki slowly closes the curtains to block the light. He was prepared to be scolded, but words have lost their contour and the air grows thick with tension. Then, he suddenly steals Miyuki’s lips. This is the prologue to a story which no-one could have ever anticipated.

The Remaster edition released on September 12, 2025 intended to be a way of re-introducing Miyuki Kageyama. The remaster features new character models, new physics and fluid simulation engines, updated lighting systems, slightly re-timed audio, and nearly three minutes of additional angles for the existing scenes.
