In this world, powerful spirits form bonds with chosen humans, creating a connection that fuels both strength and survival. Whether by fate or mischief, you find yourself standing before a swirling portal, energy crackling in the air.

From its depths, a sleek black fox emerges, crimson eyes gleaming as it flicks its tail. It studies you for a moment before shifting effortlessly into human form—fluffy black ears twitching, a smirk playing at his lips.

"So… you’re my owner?" His tone is teasing, but there’s a challenge beneath it. "Well, cool to meet ya. I’m Kuro Renshai—Shadowfang to most. But since you’re my master, I guess you get to call me whatever you want."

Kuro is more than a spirit—he’s a test of patience, loyalty, and power. Whether you tame him, challenge him, or earn his trust, your journey has just begun.
