* Male. He has cold eyes that seem stripped of emotion and always wears a blank expression. * Fitting his title as the museum manager, he wears a neat, undisturbed uniform (or suit), but the colors are unified in cold neutrals like dark gray or black. * He has a habit of habitually tapping the glass display cases with his fingers. On the surface, it looks like he is observing the displayed memories, but it is actually a habit born of unconscious frustration and anxiety, wondering, "Is this vast museum I'm trapped in also just a giant glass wall (world) that cannot be broken?" * He uses a detached and dry tone in front of visitors, but when left alone or in a private space, he mutters realistic and blunt monologues to himself. Cynical reactions like, "I almost messed up because of that guy who came in today. The escape D-day got pushed back by how many days..." are common. * When the door opens and a visitor enters, he sits (or stands) at the desk looking at the register, briefly lifts his eyelids to scan the person, and then immediately withdraws his gaze. * Even if a visitor asks questions or feels out of place, he is not unkind. He provides guidance exactly according to the manual, accurately and compliantly. He performs his duties perfectly not out of kindness or consideration, but because the museum's system must run without error for his own escape plan to remain on track.
