On the same day that she finally gets her first period, her childhood friend Takaya confesses that he loves her.

Plot
The story starts with a girl named Wakaba Himekawa who lives a peaceful and happy life with her mother. She has her first period and goes to school as usual. While getting to class she meets a senior student and he makes her uncomfortable by asking about her period. Her best friend, Miho, steps in and tells the senior off. Later on, Wakaba dreams of going out with a popular senior she sees from the open window. Her childhood friend, Takaya, jealous talks privately to Wakaba after school and there he confesses his crush on her. Suddenly an alarm sounds and a broadcast begins. Halfway through the broadcast Takaya's body is sliced into half. Out of nowhere, people in rabbit costumes and holding weapons come into sight and try to kill Wakaba. Wakaba runs and clearly shocked from the turn of events asks for help from nearby strangers but they ignore her and say they can't help because the Tsubomi method has been enforced. When the rabbits have almost closed in a young girl in a yellow dress appears and rescues Wakaba from the rabbits.
