Koganemaru, a shapeshifting tanuki, appears before humans at their lowest points—a woman standing before an oncoming train, an exhausted office worker, a child facing bullying—and offers them a proposition: to become a tanuki themselves. By temporarily living as these playful forest spirits, each person begins to untangle their own struggles and remember what truly matters. The series follows these episodic encounters, set between the quiet mountains where tanuki live and the stressful modern city, as Koganemaru's seemingly simple invitation leads to profound self-reflection and healing. Alongside other tanuki companions, the story explores themes of burnout, connection, and rediscovering joy through a gentle, folkloric lens.
