In a world of anthropomorphic animals, Belle Lablac was born as the only human being. Having no fangs, fur, or scales, she was called “Faceless,” and she lived a lonely life with no one else she could identify with.
“I want to be part of the world…”
With such longing in her heart, she decides to set out on a journey to find her roots, carrying the Runding, a great sword as tall as she is. She doesn’t know how many adversities await her along the way…
