Kitsune (Vulpes magnificus), known as Huli jing in China and Gumiho in Korea, are a type of shapeshifting fox living in certain parts of Asia.
Kitsune are famous in all the Eurasian region for having exact 899 years lifespans. Kitsune are born with a single tail and are no different from regular foxes until they completes 50 years of age, when they develops the ability of generating a green fire known as foxfire. Every 100 years of life they get a new tail and at 800 years old they become full powered Kyūbi (九尾; nine-tails).
They may use their chi, and most kitsune have knight-level mastery or higher, being extremely rare for one of them to be born a haino. Being chi users, kitsune also have the potential to become gods and many knights, paladins and sages belong to the species.
Kitsune have the ability to generate "foxfire", a specific type of Fire Sagecraft that can burn even souls. Its color may vary, and not all kitsune can use it, but certain individuals from other races may.
