Kaiju No.8: Monarch of Shadows

When the portals between worlds rupture, two realities collide. On one side, Kafka Hibino—host to Kaiju No. 8—wages war against monstrous creatures threatening Japan. On the other, Sung Jin-Woo—Humanity’s ultimate shadow monarch—reigns supreme in a universe governed by dungeons and death. But fate tears the sky open, and Jin-Woo is thrown into a world that doesn't know the meaning of mercy... or him. As Kaiju evolve beyond control and the truth behind both worlds surfaces, the line between man, monster, and monarch shatters. In a tale laced with god-tier battles, intoxicating romance, and the most seductive ecchi turns—two overpowered beings are destined to clash… or conquer together. One devours Kaiju. One commands shadows. Both will reshape reality. Brace yourself for a webnovel experience that will ruin all others. This isn’t just another crossover. It’s a war of universes. And you're addicted from chapter one.
