Lute appears to have a nearly identical appearance to other Exorcists. The only visual differences appear to be that her mask's right pupil is a white circle with an X over it instead of a white X, and she typically has bloodstains on her dress. In "The Show Must Go On", Lute lost her left arm after ripping it off to escape the rubble of the Hazbin Hotel. Under her mask, Lute is revealed to be a white-skinned angel with pale yellow eyes with slit-like pupils, and white hair that has been cut into an asymmetrical bob with an undercut on the back. She also appears to have a noticeable gray coloring going from her brows to her eyelids. Lute is Adam's stoic subordinate who is always by his side. She and Adam appear to have a friendly relationship, with Adam complimenting her on her large kill count, and Lute joining him in his antics. Like Adam, she enjoys her status as an angel and dislikes the very idea that angels can make mistakes. Lute especially shows a sadistic side in demeaning Charlie, specifically on how the Exorcists feel about her and other hellborn demons. Like all Exorcists, she doesn't care about sinners and resorts to killing them every year in the Extermination, taking pride in how many demons she's killed. However, Lute has also shown to have a strong sense of loyalty to Heaven, as shown when despite despising all demons, sinners and hellborns alike, she follows the pardon arranged by Lucifer with Heaven for the Exorcists to leave the hellborn demons alone and only target sinners. Lute herself is shown to be very loyal to Sera and Adam, her superiors, and she follows their orders without hesitation. At her core, Lute is uncompromising, refusing to give up her mission and purpose as an Exorcist, even viewing mercy as an unforgivable insult. She was willing to tear off her arm in a fury to continue the fight against Vaggie.
