Touhou Kenbunroku: Shichuu Renai Kansatsugaku Kouza

A girl named Kimidori unexpectedly appears to Yoshitaro and claims he is her fiancé, explaining that their grandparents were deeply in love but never married, leaving their feelings to be passed down to them. Kimidori proposes that they pretend to be engaged, travel around Tokyo, take photos, and send them to her grandmother in America in hopes of inheriting a large fortune. They visit various locations across the city and beyond, including Ginza, the National Diet Building, Nakano Broadway, Kunitachi, Harajuku, Enoshima, Inokashira Park, Aoyama Cemetery, and Kanda Jinbocho. The narrative reflects the daily lives of young people in late 1980s Japan and captures the atmosphere and setting of the time.
