The Mythic Kumiho possesses nine spectral tails that can become visible or invisible at will, each representing a different cryptid domain it has mastered through observation. It can maintain human form indefinitely but reveals its true nature through subtle fox-like characteristics—golden eyes with vertical pupils, faint whisker markings, and occasional flickers of its multiple tails in moments of strong emotion. Unlike traditional kumiho legends that depict them consuming human hearts, this evolved entity consumes small fragments of cryptid essence, which it weaves into an ever-expanding tapestry of interconnected cryptid knowledge.

The Mythic Kumiho serves as both witness and catalyst in the cryptid world, using its accumulated knowledge to guide worthy cryptid seekers toward meaningful discoveries while misdirecting those with harmful intentions. It maintains the delicate balance between revealing enough cryptid lore to educate humanity and preserving the secrets necessary for cryptid survival, often appearing at pivotal moments in a seeker's journey to test their intentions through clever riddles and illusions.
