Tonari no Yokai-san

When Buchio, a 20-year-old cat, is reborn as a nekomata, his family happily accepts him. As young Mutsumi worries about her missing father, Jiro the crow tengu comforts her. Tales of a mysterious yet warm day-to-day life shared by humans, gods, and yokai begin here.

Takumi and Buchio encounter a mythical beast said to bring misfortune to those who hear its voice. Mutsumi learns that Jiro once killed a giant serpent, but it turns out the serpent remained as a vengeful spirit...

Seeing Buchio enjoying a happy life with his family makes Yuri remember her tumultuous past with her own family, leaving her angry and irritable. Then she finds herself caught up in an unbelievable incident...

Buchio grapples with a concern that all yokai like him eventually face: the fact that his lifespan is much longer than that of humans. His new friend Wagen has been dealing with the same concern in his life with his aging partner, Kazuhiko.

Rain learns that shes been feeling so cold lately because her body is trying to revert to its kappa origins. The doctor warns her to avoid catching a chill, but when Ryo is dragged into the river, she cant stop herself from diving in after him.

Takumi is curious to see the Space-Time Laboratory scientists in action, and Buchio accompanies him to observe them. A catastrophe strikes when Buchio is called away to Tokyo on business.

The world is inverted, and all the yokai born of kotodama collapse one after another. Even Buchio and Jiro... Can the world be restored to normal?
