The bishop, who wanted to become the pope, was said to be the representative of the Caro Kingdom's Church of the Sun God.[1] The bishop purchased the Night's Exultation for 23 billion counds from Cale in order to get his hands on a divine item.
The real bishop: The Caro Kingdom’s bishop was a skinny woman in her thirties with a sharp gaze. That was her true appearance.
The current bishop killed the actual bishop and was impersonating her.[2]
