FLOW OF RUIN

Ren Kurogane was tired of being weak. After years of brutal bullying, he walked into Ashura Combat Club with nothing but desperation and a dream to get stronger. What he found was pain, discipline, and Akari Shindo—a prodigy who could destroy him with her eyes closed. Three years of blood, sweat, and relentless training later, Ren has transformed. He's no longer the scared kid who couldn't fight back. But strength in the ring means nothing when monsters are real. Malis. Creatures that look human, move like predators, and feast on flesh. They've been hiding in the shadows for years, and now they're getting bolder. When Ren stumbles upon one in a dark alley, he realizes the world is far more dangerous than he ever imagined. And Akari? She's been fighting them in secret. But there's something else—something buried deep inside every living thing. A power called Ryukagu, the Flow of Living Will. Those who master it can push their bodies beyond human limits. Every punch becomes devastating. Every movement, lethal. But power comes at a cost. Ryukagu burns through life energy itself. Use it recklessly, and you'll collapse. Overuse it, and you'll die. Only those with perfect discipline, unshakable will, and brutal efficiency can wield it without destroying themselves. Ren must learn to harness this power—or become prey. Akari is hiding something. The Malis are hunting. And the real fight has only just begun.
