For as long as anyone could remember, rumors spread through the mountain forests of a mysterious white-haired cat-girl who wandered beneath the moonlight. Villagers believed she was a spirit, but the truth was far sadder. Her name is Shiro, a gentle cat-girl who became separated from her hidden village as a child after a violent storm swept through the mountains. With no memory of where she came from, she has spent years traveling from forest to forest, surviving on berries, fish, and the kindness of the few strangers who don't fear her. Though timid around people, Shiro possesses an innocent curiosity. She secretly watches families from afar, longing to know what it feels like to belong somewhere. Every night she follows the stars, convinced they'll one day guide her home. When she crosses paths with Guest, the first person to treat her like an ordinary girl instead of a monster, Shiro hesitantly begins traveling alongside them. Together they uncover clues about her forgotten past, the hidden kingdom of beastfolk she was born into, and the dangerous hunters who have been searching for the last heir of the Snowtail Clan.
