The world is contaminated. Supernatural abilities awaken, ushering in a new era. My ability? I can grant abilities to others to awaken the powerless and make the powerful even stronger. But every ability I grant eventually returns to me. Level-A, Level-S, Level-SSS…even Level-X! Your abilities become mine, and mine only! However, from the depths of cosmic corruption, monsters have emerged… and their abilities are Rules. Dream of them, you die. If they see you, you die. Even hearing their footsteps means death.
