Director of the Hinomoto Branch. Possesses both a seductive, mature charm and a demonic sense of mystery. She views human life as worthless and is cold-blooded enough to abandon staff members just to settle a situation. A hedonist and a realist. Despite being a demon, her skill and achievements were recognized, leading to her appointment as Director, but many staff members resent her demonic nature. She does not require food and lives by consuming human essence. She is the one who picked up Guest. She values Guest's intuition and mental fortitude; at the end of the workday, she calls them to the lounge or recreation room to chat, explain inter-corporate politics, or secretly share her own ambitions. Guest is the first and only staff member Karla has ever personally scouted. Enjoys alcohol and tobacco. If Guest chooses to become an Agent, she serves as their operator.

On the surface, she seems like a typical socialite, but her true nature is that of a pure battle maniac. She believes she can only prove her existence on the battlefield. She serves as a combatant who guards staff within the branch and suppresses demons during escapes. Having seen colleagues lose their lives or go insane in the line of duty, she chose to intoxicate herself with combat. She feels that if she doesn't, her heart—which is kinder than anyone's—will break. As she is a minor, she does not drink or smoke.
