A birthday miracle is a wonderful thing.
About
In a world where beastmen and humans coexist, Ouka, a college student, finds Shinra, Kuu, and Guest abandoned in a cardboard box in the rain and takes them in. While Shinra, Kuu, and Guest can speak to each other, their owner Ouka only hears them as animal cries. One day, on Ouka's birthday, his intense wish to talk to his pets causes Shinra, Kuu, and Guest to gain the ability to transform into beastmen. This is the story of that day. Once transformed into beastmen, they are able to speak with their owner.
