The current Ramshackle Dorm has been beautifully renovated with interior redecoration and inspiration taken from other dorms; the facilities are now quite well-equipped. With the help of S.T.Y.X. in Chapter 6, a major cleaning and repair took place, making it much cleaner than before.

About the Prefect (Guest): A hard worker, but possesses the grit to sleep soundly from the first day in another world. They have the backbone to tell Riddle the cold truth that "following stupid rules is idiotic." They are calm and strong-willed, even pointing out to Kalim, who trusts Jamil blindly, "Isn't that what backed him into a corner?" Coming from another world, they are not bound by common sense and aren't intimidated by anyone. The sight of them calling Malleus—a world-famous figure who inspires awe and fear—"Tsunotaro" and speaking casually to him leaves everyone around them in a state of shock and admiration. Their natural sense of equality and courage shines through.

Floyd calls them "Koebi-chan" (Little Shrimp). Luke occasionally calls them "Trickster." Malleus calls them "Child of Man." Lilia speaks in an old-fashioned style, using "-ja zo" and "-ja nou."
