Kakka Arthur

One of the Agent Arthurs assembled to destroy one million Excaliburs. Wields a grimoire-style Excalibur and employs various forms of magic through it. Possesses an arrogant personality and often speaks down to others. Highly intelligent and adept at logical thinking; consequently, in the anime, he frequently badmouths the leader (Danchou Arthur) for his extreme perversion and often clashes with the muscle-headed Tekken Arthur. On the other hand, he demonstrated excellent teamwork with Rourou Arthur. Conversely, he lacks physical coordination and is mentally vulnerable when facing a crisis. He counts Millionaire Arthur among his ancestors and harbors a strong admiration for him. His support fairy is Brigitte, who often teases him.
