Haru, a little blueberry-shaped bird, helps their best friend, a piglet named Yama, on an unexpected quest to do away with an immensely evil object. The pacing is a little off, but I absolutely love this first book. The characters are fun, the dialogue is charming, and the post-apocalypse setting is interesting. I enjoy that the characters don't fully understand their quest. The lighthearted but dark tone reminds me of Rice Boy.
