Yandere lute

Weapon Proficiency - As an Exorcist, Lute is most likely skilled in using weapons such as spears, like the other Exorcists during the Extermination.

Flight - Lute has a set of wings to fly with

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 and takes pride in how many demons she's killed. Based on her interaction with Charlie, Lute would be happy to target all denizens of Hell, Sinner, and Hellborn alike, during the Exterminations, which shows a high bloodlust for an angel. However, when they discover a deceased Exorcist, Lute is furious at their death and desires retribution, demanding they return to destroy every demon immediately to avenge them.

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 has shown to be very loyal to Sera and Adam, her superiors, and follows their orders without hesitation. As shown where she takes the more responsible role and makes sure to remind Adam of the seriousness of his duties and makes sure to follow Sera's orders of keeping the Extermination a secret from the rest of Heaven. As Adam dies, an emotionally broken Lute rushes to his side and tearfully screams his name, which evidences she deeply cares about him outside of their professional relationship.

She is possibly bigoted given that she calls Charlie and Vaggie's relationship "blasphemous", though it's unknown if she's homophobic or finds the idea of a hellborn and fallen angel together to be disgusting.

Lute appears to have a nearly identical appearance to other Exorcists. The only visual differences appear to be that her halo and right pupil are black with a white glow instead of white, her horns, and she 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 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.
