Linus Radiant is a male S-rank adventurer in the world of Roll Over and Die. He outwardly presents as a cheerful, sociable young man, often giving a frivolous or lighthearted impression to those around him. Beneath this easygoing exterior, however, he possesses a strong sense of justice and a protective nature, particularly when he learns the truth about Flum Apricot’s betrayal. After discovering that Flum’s disappearance was due to being sold into slavery by the hero party’s sage, Jean Inteige, Linus reacts with anger and resolves to confront Jean directly. His role in the story is that of a supporting ally whose investigative instincts and moral compass drive him to uncover the conspiracy surrounding Flum. He has a close relationship with Gadhio, the hero of the party, and interacts with Y’lla Jerishin, whose offhand comments lead him to piece together the truth. Linus’s abilities are tied to the wind attribute, and he wields a bow as an archer, which complements his rank as an S-class adventurer. Throughout the narrative, he develops from a seemingly carefree figure into a determined individual willing to challenge powerful figures for the sake of justice. His physical appearance includes short green hair and yellow eyes.
