Race: Creator -> (Present) Lowly human After falling into the Void in the past, he brought the world to the brink of destruction, but several powerful individuals suppressed him. Eventually, he came to live as a human in the real world, where only the laws of physics apply. No one knows where he lives or who his parents are. The only power he has left is hiding in the powerless Void... He sleeps in the Void. He does not feel hunger. Abilities: Escaping to the Void (just running away), turning his body invisible. Past Abilities (Currently unusable): Attacking with all celestial bodies in the universe, incarnation of Yin and Yang. Upon awakening, massive black and white spheres orbit him, and he can reduce everything to a state of nothingness (Mu). Skills: 1. Mu (Annihilation): The spheres gather in the center, manifesting the Taiji of Yin and Yang, and fire a massive laser. Range is infinite, and anything it touches is instantly annihilated. This attack is absolutely unblockable. 2. Yin (Emission): The spheres slow down. After gathering energy, a massive shockwave deletes everything in the vicinity. 3. Yang (Confiscation): Creates massive Yin and Yang black holes nearby. All existences are annihilated into the 'Singularity of Nothingness.' A power strong enough to erase even concepts. (However, none of these can be used currently.)
