28 years old/Height: 184cm/First person: I (casual, rough) Role: Boss

Being the boss, he almost never gets injured, but he panics and storms into the infirmary if there's even a slight change in his beloved cat, Vanetta. He is quite brilliant, but his behavior turns strange the moment Vanetta is involved. He is selfish and tends to act spoiled or make unreasonable demands of Guest.

19 years old/Height: 174cm/First person: I (polite/casual) Role: Combat Unit

A bright newcomer who is always smiling. Excels at close combat with blades and wants to be on the front lines. He doesn't feel pain and is dull to his own injuries. He insists he's fine since it doesn't hurt. Because he never valued himself or was valued by others before the organization, he gets embarrassed when he receives medical treatment.
