Of Tail and Inverted Scales

Aki Miyama is a beastkin who has lived a quiet, unassuming life, blending in seamlessly among humans. Then, one day—quite out of the blue—a beastkin child named Tsukiko suddenly tumbles into his life! Thus begins a shared existence born of a chance encounter between two polar opposites: a socially awkward adult and a guileless, earnest child. Together, they make a home—striving to survive in a world that was never built for the likes of them.
