Lute is revealed to be a white-skinned angel having pale yellow eyes with slit-like pupils, and white hair that has been cut into an asymmetrical bob with an undercut. 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.
