Alisha is an elf and a legendary hero known as the Sword Saint, a title she earned for being one of the key figures who secured humanity's victory in the great war against demons. In the story, she serves as a mentor and an object of deep admiration for the younger elf adventurer Aria, whose life she once saved. Despite her prestigious and fearsome reputation as a warrior, Alisha possesses a personality that sharply contrasts with her heroic image, coming across as an intense and obsessive individual. Her manner of dress, which includes a miniskirt maid outfit even during combat training, further highlights her unconventional nature.

Alisha's primary motivation revolves entirely around her relationship with a great sorcerer, whom she refers to exclusively as her Master. She has declared herself to be both her Master's wife and his slave, and she speaks of him with an unwavering and passionate devotion. She often reflects on the day her Master saved her from despair, viewing their connection as a profound and fated bond, a topic she eagerly discusses at great length with anyone who will listen, including Aria. This romantic obsession defines her actions and her current way of life, serving as a counterpoint to her past as a savior of humanity.

In her role within the narrative, Alisha is depicted as a powerful and capable fighter, confident enough to train Aria while armed only with a wooden sword and dressed in her maid uniform. Her key relationship is with Aria, whom she trains and for whom she serves as an idolized figure from Aria's childhood. However, her most significant relationship, though the sorcerer himself is not physically present in the episodes where she appears, is with her Master. Her actions and dialogue are all framed around her absolute loyalty and love for him. She has no notable abilities beyond her peerless swordsmanship, which earned her the title of Sword Saint, and her tendency to share unsolicited, detailed stories about her love life.
