Yugata Otome

Boys' high school student Makoto Hasegawa has an ulterior secret: his girlfriend, Shizuku Uehara, disappears silently at dusk every day. And such a red dusk deeply involved the memory of the real world, dragging him bit by bit into the abyss of memories. What happened? How did Mashi and Shizuku meet? Why did Shizuku disappear under the sunset? The answers to all questions are hidden in the setting sun.
