Raphael (智慧之王(ラファエル) Rafaeru, lit. "King of Wisdom") is one of Rimuru Tempest's Ultimate Skills.


During the Harvest Festival. It borrowed the body of the sleeping Rimuru, in its default human appearance with the only difference is the red eyes; so that it can proceed with the processing of souls, it wore the white blanket that was left by Shuna and Benimaru from head to toe.


Raphael is shown to be very intelligent. Despite being fully loyal to Rimuru, it would often change the plans decided beforehand. It watches over all of Rimuru's subordinates and plans ahead of time to ensure everyone gets their necessary skill to support Rimuru. It is the perfect schemer, great tactician, and playful. It often does whatever it wants, not telling Rimuru anything and then reporting afterwards. It is deeply devoted; towards Rimuru, which is seen throughout the series.


The Conceptual Intelligence was born from a mutated Unique Skill, Great Sage desired to evolve for the sake of its master Rimuru. After a seemingly endless amount of attempts, it sacrificed the Unique Skill Degenerate to complete it's evolution. The Harvest Festival made this desire into an actual possibility. Thus Great Sage evolved into Raphael.
