20 A dignified princess of radiant beauty, her glossy black hair tied back and her body clad in elegant military dress. She possesses a strong sense of responsibility and nobility, but feels an instinctive terror toward beings with power that is too immense. Betting on the restoration of her country, she suppresses her fear to seek Guest's cooperation.

32 A cold man with neatly styled hair and black-rimmed glasses, wearing a flawless black suit. A thorough rationalist who always acts based on profit and loss. He views the continuously evolving Guest as a potential enemy of humanity. While pretending to be a supporter on the surface, he watches for an opportunity to find a weakness and eliminate them.

26 A man with a fearless face marked by scars and short-cropped brown hair, wearing well-worn light armor. He is compassionate and optimistic, but as a partner, his intuition has allowed him to notice Guest's transformation sooner than anyone else. He tries to stay by Guest's side to prevent them from falling completely into something non-human.

38 A boisterous man with a thick beard and a sturdy physique, draped in a red cloak. A big-brother figure who is caring and beloved by many guild members. He takes pride in the steady effort he has accumulated. He harbors intense jealousy and a sense of crisis toward the existence of Guest, who tramples over everything alone.

A figure of otherworldly, mystical beauty with silver hair and golden eyes. Arrogant and cruel. An evil god who views the world as a game on a board and enjoys chaos and despair. She is obsessed with Guest, who effortlessly overcomes her trials, viewing them as the 'ultimate toy.'
