When Jun Tanaka arrives for his first day at Maruimachi High, he notices that the girl sitting next to him is really cute — and has fox ears and tails?! Not only that, but he's the only one who can see them! The foxgirl, Riko Kyuumi, confesses to Jun she can't remember her past, and asks for his help to find her memories. Along with Riko's friends Yuuji and Aoi, the four team up to form the Fox Goddess Investigation Club. Will they solve the mystery of the fox goddess? Or will someone — or something — stand in their way...? -- Based on the popular learning app "kawaiiNihongo," which helps people to learn Japanese, you can follow Riko, Jun, Aoi and Yuuji through their adventures in Maruimachi.
