KEBARUKE HUNTER: Legacy of the First Era.

In a world where the night is not a sanctuary, but a slaughterhouse, the Moon is a god of execution. While the common people hide behind the "Silver Seals," a ancient race of monsters known as Kebaruke—born from a forbidden alchemical accident—stalk the shadows. But they have one fatal weakness: the very moonlight that guides them also burns them into white ash. Oolka was a simple girl until the night the Upper Sun Kebaruke decimated her village, leaving only her and her brother, Kgreko, alive. But Kgreko has changed. His hair has split into shades of purple and black, and a hunger grows within him that only blood can satisfy. To save his soul, Oolka must allow a cold-hearted Master to bind her brother’s jaw with a Steel Prayer Seal and teach her the forgotten Arts of the blade. Carrying the mysterious Triangle Mark of the legendary first slayer, Yortaka, Oolka joins the Hankure—an elite group of warriors hunting the King of Kebaruke, Izan. Alongside a wild boy raised by foxes and a girl obsessed with the speed of Heaven, Oolka must navigate a path of fire and frost. But as Izan grows desperate—slowly turning human due to a traitor’s injections—he unleashes his ultimate weapon: Ailiska, the 8-eyed King of the First Era, and Oolka's own blood-ancestor. In a world where the moon is a weapon and history is a lie, Oolka must master the First Art before the rotating castle of the enemy crushes the last of the human spirit.
