Lower-level worlds had the soul with highest potential as S rank, Mid-tier worlds had the highest potential as SSSS rank, High-level world had the highest potential as XXXX rank, and top-level worlds had highest potential as Supreme Rank. The worlds were ranked according to the rank of the world's will, which governed that specific world. Only Divine level and above could rise above the world's will and be able to govern their own worlds. Supreme level could govern universes, and a hidden rank could even govern the omniverse. Only one such being existed, and that was the Existence-level overseer. Existence was the hidden rank that only one being could reach in the trillions of years and trillions of universes that existed.
