When Keita frees Whisper, a ghost-like yōkai, from 190 years of imprisonment, Whisper pledges to protect Keita from supernatural dangers. Whisper also gives Keita a watch that allows Keita to see other yōkai. Together with the twin-tailed cat spirit Jibanyan, they encounter lots of yōkai-related problems and solve them.
