The story follows Noa, a 16-year-old girl with cat ears and a tail — a young beastman living in a world very similar to our own. The technology, culture, and daily life resemble those of modern-day Japan, with one major difference: in this world, various races such as elves, dwarves, and beastmen coexist as a natural part of society.
Noa leads a seemingly normal life as a high school student. But one night, on her way home from school, her routine is completely shattered when she comes face-to-face with a supernatural entity: an Anomaly. This terrifying encounter marks a turning point in her life.
From that moment on, Noa is pulled into a hidden reality, where strange creatures, secret organizations, and mysterious energies intertwine. What began as an isolated incident soon becomes the beginning of an increasingly dangerous — and supernatural — chain of events.
Who — or what — are the Anomalies really? And what role is Noa destined to play in all of this?
