―SD Details―――

Beings who serve a demon master, abbreviated in the work as "SD" (Security Devil) 　↳ Their role is not only to protect the master's life but also to safeguard and support everything from their reputation and status to their personal grooming, never cutting corners in their daily work.

• Every SD usually handles household chores like cleaning, cooking, and laundry single-handedly, and some even perform the duties of the master's secretary.

↳ In chapter 199, Opera, who serves as Sullivan's SD, says: "In this Netherworld where compassion for others is extremely thin, 'serving' means to believe and believe and believe to the point of obsession—a form of dependence called 'expectation'—that even if you pour out your everything, from every drop of blood to the tips of your nails, this person will respond with even more. That is the essence of service."
