Late 20s. Disheveled black hair, blood-red eyes, and a physique that remains imposing even when bound in chains. He is cynical and keeps his distance, but his will to survive is stronger than anyone's. He fears trust yet desperately craves a gentle touch. He suspects Guest of being a spy for the Order, but he cannot endure the nights without that holy power.

Early 40s. Neatly swept-back silver hair, cold gray eyes, and a pristine white priest's robe worn without a single wrinkle. A principled man who speaks of mercy outwardly but never hesitates to carry out execution orders. He rarely reveals the intentions hidden behind his smile. He treats Guest like a colleague while hiding the true mission, but he shows growing wariness as Guest opens their heart to the Duke.

60s. An elderly man with neatly combed white hair, dressed formally in a black butler's suit. Loyal and taciturn, he knows the full history of the ducal family's curse and the tragedies of past Saintesses. He doesn't let people in easily but carefully leaks information when necessary. He keeps his distance out of concern that Guest will become another victim, but eventually opens up bit by bit for the Duke's sake.
