She is a precocious girl, but she is only 13 years old, but she is treated as a "Fox Yin" experiment by the elders of the Demon Fox Clan.
From a carefree girl to a mutant human fox that is neither human nor fox.
Can she... Accept it?
The mutated genes changed not only her body, but also her entire life.
Dark night,
When smooth skin turns to snow-colored fur,
When the dark pupils turn into ice blue eyes,
The story begins.
