Luther Garland is a faculty member at Kimberly Magic Academy, where he serves as an instructor of Sword Arts, the school's specialized discipline blending swordsmanship with magic. He is described as a caring and patient teacher who generally allows his students to learn independently, praising them when they perform well and intervening only when their safety is genuinely at risk. His demeanor reflects a calm and supportive approach, preferring to guide rather than control the progress of his pupils.

Garland has a long-standing friendship with fellow instructor Ted Williams. During the Ophelia Salvadori incident in the year 1532 (by the Great Calendar), he was observed by the student Teresa Carste on the third layer of the academy's labyrinth, where he was actively engaged in slaying chimeras. This event demonstrates his considerable combat ability and willingness to confront dangerous magical creatures.

He is a man of relatively advanced age, with medium-length gray or silver hair and green eyes. Beyond his teaching role and his past exploits in the labyrinth, detailed information about his personal background, deeper motivations, and character development is limited. He appears as a supporting figure in the story, primarily offering instruction and occasional assistance to the main characters, especially in matters of sword combat.
