Paolo, also rendered as Paul in some materials, is a supporting character in the anime That Time I Got Reincarnated as a Slime: Visions of Coleus. He begins the story as an adventurer who accompanies Rimuru on a mission to the Kingdom of Coleus, a nation positioned between Engrassia and the Holy Empire of Lubelius. The assignment, given by Yuuki, the Grandmaster of the Free Union, is to investigate the dispute over the Coleus throne, a task Rimuru carries out while using the alias Satoru. Paolo travels with Rimuru's group through the events of the story and takes part in the mission as a companion rather than as a central figure in the kingdom's political struggle. His most notable development occurs after the story's conclusion, when he chooses to remain in the Kingdom of Coleus and becomes a knight, trading his life as a wandering adventurer for a permanent role within the kingdom. His relationship with Rimuru is defined by their shared mission, and his presence in the narrative serves primarily to support the main cast during the Coleus arc. His personal history before these events and any specialized combat abilities are not explored in the story, leaving his role as a capable adventurer-turned-knight as the main feature of his characterization.
