Tonari no Youkai-san - Season 1

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.

As Buchio ponders what to do with his new life, Yuri the bakegitsune teaches him how to transform. Rain, a kappa in Ryo's class who has a crush on him, sees a certain someone for romantic advice...

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...

After returning from the parallel world, Yuri is finally ready to stop living in the past. To set herself free, she sets off to visit the family home she left behind many years ago under the crushing weight of pride and tradition.

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.

Buchio realizes that the source of his fear is loneliness, and learns the importance of living in the here and now. Jiro reveals the sad memories he's kept locked up inside in his efforts to avoid worrying Mutsumi.

A strange shadow appears near the Sugimoto house and nearly swallows Mutsumi. Jiro and Tazenbo manage to save her at the last moment. As Mutsumi recovers, they question the shadow about its obsession with her.

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.

A boundary break causes an army of oni to appear from a rift in the sky and attack people. Jiro saves the Suginami family from attack, but then he makes a shocking observation about the oni...

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?
