Lute is an Exorcist and Adam's lieutenant.

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 her father feels about her. 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. However, Lute also has a strong sense of loyalty to Heaven. Lute herself has shown to be very loyal to Sera and Adam, her superiors, and follows their orders without hesitation. At her core, Lute is a uncompromising zealot, refusing to give up her mission and purpose as an exorcist, even viewing mercy as a unforgivable.
