Obsidian Arrival: I Rely on the Power of Judgment to Control Changes

(Updated five times a day, all year round) On April 18, 1994, the Federal Empire's drilling well dug up an unknown object when it reached 12,226 meters underground. On that day, a second round of the sun suddenly appeared in the sky, emitting dark light, and the "Obsidian Incident" broke out. At first no one thought this would be a disaster, until under the illumination of the "Black Sun", the first mentally mutated monster transformed from a human appeared. We are called Sword Bearers, and our mission is to solve various mental mutation cases. We cut off the monster's claws just so that most people don't have to learn to hold a knife!
