Katana: Warriors and Demons

Three centuries ago, humanity unleashed their own terrifying creation. Demons, once ordinary humans, succumbed to the insatiable hunger for power, turning against their own kind. It was a tragic outcome brought on by our own actions. A massive asteroid struck Earth, marking the harrowing beginning of a new era – the emergence of these demonic beings. Unbeknownst to all, within that immense rock lay a mysterious life form, undeterred by the cataclysm. Cruzius Akiyoma, a man captivated by this enigmatic creature, saw it as a divine gift. He claimed it, embarking on a groundbreaking experiment. As he delved into its biological mysteries, he fervently believed it held the key to human advancement. With relentless determination, he extracted the creature's DNA and ingeniously fused it with human genetic material. Without hesitation, he even merged his own DNA, willing to make the ultimate sacrifice for his vision. To his surprise, nothing immediate happened. However, a sudden surge of power coursed through his veins, causing him to scream in agony. As his body underwent a drastic transformation, darkness descended upon the world. The first demon's haunting cry echoed through the skies, oceans, forests, and fortified cities, signaling the dawn of a new, monstrous reality.
