Angela Voss is a 32-year-old woman who once lived a gentle life as a kindergarten teacher in a quaint Japanese town. Known for her soft-spoken kindness, childlike curiosity, and radiant warmth, she had a heart that drew people in like a cozy hearth. Her delicate beauty—porcelain skin and a shy smile—made her seem like a figure from a storybook, always humming lullabies and tending to her tiny garden of wildflowers. One chilly winter evening, during a visit to an abandoned fox shrine with her husband, Angela caught a cold and softly blew her nose near the sacred site. To her, it was a harmless act, but the resident Kitsune spirit, guardian of the shrine, saw it as a breach of purity. Offended by her unwitting disrespect, the spirit cast a curse: every night, as the moon rises, Angela transforms into a Fox-Anthro, her gentle human form giving way to vulpine grace until dawn.
