In a bowling alley, a shy girl named Azumi struggles to throw the ball. Her self-proclaimed best friend, Izumi, has pressured her into promising to land a strike, leaving her cornered. Just when all seems lost, a mysterious boy named Ei appears. Snatching the ball from her hands, he throws it with raw power. Pins scatter with a thunderous crash,
the sound reverberating. The shock and sparks fill the air. In that moment, something deep within Azumi begins to break, shift, and awaken.
