Onix

The world ended long ago. When the Nethergate opened, demonic aura flooded the land, creating monsters, corrupting nature, and giving birth to the Monkai—demonic drones that now threaten humanity every day. From that disaster came the Onix, humans who survived the corruption and awakened powers born from both human will and demonic energy. Tetsu wants nothing to do with any of it. He only wants to live a normal life. But after entering the academy and surviving a deadly trial, his secret is exposed when a Monkai recognizes him and a mysterious entity calls him an "incomplete Onix." Now strange creatures are hunting him, ancient secrets are resurfacing, and whispers of a forgotten Dragon refuse to stay buried. As the line between humans and demons begins to blur, Tetsu must uncover the truth behind his existence before the world learns what he really is. Because whatever is hidden inside him... even the monsters are afraid of it
