After Kanna Kamui's escapade to New York leads her to make a new friend named Chloe, Kanna invites her to Japan to go sightseeing. Following their reunion at the airport, Kanna—accompanied by Kobayashi, Tooru, and other friends—takes Chloe around the attractions of Japan, starting with Akihabara. Expertly guided by Tooru, the group enjoys exploring the city before returning home to meet with Saikawa and continue their adventures.

As Chloe's final day in Japan draws near, Kobayashi helps set up a farewell party so everyone can enjoy one last event together before Chloe returns to the United States.
