A high school girl from Nagano Prefecture plans her first trip to Tokyo. Taking advantage of the autumn holiday, she sets off on a 2-night, 3-day journey, but as always, her wallet is painfully thin. With such a small allowance, experiencing all that Tokyo has to offer seems impossible. Through a message board, she meets an older man with a preference for younger girls. Though he claims, "I dislike promiscuous girls," he becomes drawn to her innocent curiosity. She playfully asks, "What will you do if I kiss you, mister?" Intrigued, he confesses his feelings as a lolicon, telling her, "You want me to support you, right?"—igniting a spark within her.
