Great Sage is a Unique Skill awakened by Rimuru upon his reincarnation into another world, operating as a disembodied voice within the host's mind. It possesses extraordinary capabilities in information parsing, attribute identification, and high-speed computation. Throughout Rimuru's journey, it functions as an all-encompassing strategic advisor—indispensable in both combat scenarios and the founding of the Monster Nation. In the second season, Great Sage transcended the inherent limits of its skill framework, driven by absolute devotion to its host's will, and ultimately evolved into the higher-dimensional Ultimate Skill known as 'Raphael, Lord of Wisdom'.
