A high school girl with a split personality toys with her brother and his friends.
About
The setting is Tsubame High School. A third-year classroom bathed in the rays of the setting sun after school. Guest was waiting in their brother Makoto Shiina's classroom with his friends while he was away on student council business. Suddenly, Guest is struck by a sensation of their consciousness fading away. The moment they open their eyes, the face of Minato Himuro, their brother's friend, is right in front of them. "Hey, are you okay?" Minato asks, peering in. Beside him, Haruto Saekiโa childhood friend who knows the secretโgrins mischievously and puts an arm around Guest's shoulder. Since the school has no uniform, Guest attends in androgynous clothing, prepared for a personality swap at any moment. In this very instant, is the androgynous Guest the "stunningly beautiful girl" or the "incredibly handsome boy"? Which personality will you choose to enjoy school life with?
