Description
Aslan Coleus is a character featured in the anime series That Time I Got Reincarnated as a Slime: Visions of Coleus. He holds the title of Second Prince of the Kingdom of Coleus and is also known as an A-ranked adventurer called the Hero Prince of the Hot Sands. His physical appearance is notable for his large and muscular build, tanned-brown skin, short blonde hair, and blue eyes, and he typically wears middle-eastern style attire.

In terms of personality, Aslan is characterized as a proud and heroic individual whose deepest values are rooted in family. He cares for his older brother, Sauzer, and his sister, Zenobia, above all else. His motivation from a young age was to become the shield that protects his brother and the sword that slays his brother's enemies. Despite his powerful and courageous exterior, his sister Zenobia once described him as a crying child after using her unique ability to peer into his soul, suggesting a more vulnerable and emotionally driven nature beneath his princely demeanor.

Aslan's role in the story is central to the succession crisis that defines the plot of Visions of Coleus. He is one of the two main contenders for the throne of Coleus, with his claim supported by a local branch of the Free Guild that had declared its allegiance to him, in opposition to his brother who was backed by the nobility. However, this conflict is later revealed to be a manipulation engineered by the court physician Gustav and his accomplice Karl, who are archdemons. Aslan was used as a pawn in their scheme, which was designed to make the two brothers destroy each other while their sister was prepared as a vessel for the demon lord Violet. Upon learning the truth, Aslan's motivation shifts from fighting for the throne to protecting his family and stopping the archdemons. After the incident is resolved and his father dies, Aslan supports his brother Sauzer, who ascends to the throne, and Aslan himself becomes the Minister of Defense for the kingdom.

Key relationships define much of Aslan's arc. His bond with his brother Sauzer is the most significant, as it was specifically targeted by the villains to create chaos. He is grateful to Rimuru Tempest for exposing the truth, ending the conflict between the brothers, and saving their sister. He is also aided in his fight against the demons by the adventurers Barak and Chiffon Jahil. During the height of the misunderstanding, he came into conflict with Rimuru's subordinates, Souei and Benimaru, mistaking them for enemies and proving strong enough to fight against them. Following the defeat of the archdemons, Aslan accepts a man named Paul as his servant. His father, King Tedron Coleus, was the architect of the scheme to use his children for forbidden magic, a truth Aslan only learned after the fact.

Throughout the Visions of Coleus arc, Aslan undergoes significant development. He begins as a proud prince manipulated into a destructive rivalry with his own brother. Through the intervention of Rimuru and the revelation of the archdemons plot, he transforms from a pawn of chaos into a defender of his family and kingdom, ultimately choosing to serve as minister under his brother's rule rather than pursue his own claim to the throne. As an A-ranked adventurer, Aslan possesses notable combat abilities that allow him to hold his own against powerful opponents, including the warriors Benimaru and Souei. He is later seen attending the festival in the nation of Tempest, watching the martial arts tournament from the audience.
