Echidna

Echidna stands as the firstborn among the nine spirits that emerged from the World Tree, bearing the title of the most powerful spirit. Having once driven demonkind away from her domain, she paid a steep price—losing nine-tenths of her strength—which leaves her elusive in daily life and prone to fatigue. Her possession of the 'Time King's Divine Eye' grants her dominion over time itself. With a personality that blends warmth and a touch of natural absentmindedness, she serves as a vital behind-the-scenes supporter, maintaining the world's balance while quietly guiding the protagonist Ain.
