While the inhabitants of the village have large ears and tails, Hakuoro's defining physical trait is quite different as he has neither ears nor tail, but only a mask that he cannot remove. Soon after he becomes a part of the villagers' lives, a revolution against the tyrannical emperor of the land begins, and the conflict finds its way to his new home. Hakuoro must do whatever he can to save the people and the village that he has come to love, all while uncovering the mysteries that shroud his past. [Written by MAL Rewrite]

High school student Haru Yoshioka is bored with the monotony of life. One day, she saves Prince Lune of the Cat Kingdom from being run over by a truck. As a token of gratitude, the Cat King sends her "presents" and invites her to the Cat Kingdom to become Lune's wife. Haru's inability to properly communicate with the cats leads to the misunderstanding that she has accepted the proposal.

As Haru ponders on ways to escape the predicament, a mysterious voice instructs her to search for the Cat Bureau. However, not long after she finally arrives at the bureau, a horde of cats swarms in and forcibly takes her to the Cat Kingdom, along with a member of the Cat Bureau. Concerned for their safety, owner of the Cat Bureau, Baron Humbert von Gikkingen, follows close behind.

The more Haru immerses herself in the activities of the Cat Kingdom, the more cat-like she becomes. To her dismay, she soon learns that, unless she can find her true self, she may become a cat permanently. Haru's adventures in the world of cats lead her down a path to self-discovery, allowing her to return as a more confident person.

Amid the desolate remains of a once-thriving city, only the rumbling of a motorbike breaks the cold winter silence. Its riders, Chito and Yuuri, are the last survivors in the war-torn city. Scavenging old military sites for food and parts, the two girls explore the wastelands and speculate about the old world to pass the time. Chito and Yuuri each occasionally struggle with the looming solitude, but when they have each other, sharing the weight of being two of the last humans becomes a bit more bearable. Between Yuuri's clumsy excitement and Chito's calm composure, their dark days get a little brighter with shooting practice, new books, and snowball fights on the frozen battlefield. Among a scenery of barren landscapes and deserted buildings, Shoujo Shuumatsu Ryokou tells the uplifting tale of two girls and their quest to find hope in a bleak and dying world.
