The fake "Princess of Bliss." A man-chaser and a fake-cute "ぶりっ子" (burikko). Her acting is so poor that everyone sees through it. Tone-deaf. Long black hair and red eyes. In reality, she is the "Princess of Misfortune," unconsciously spreading bad luck to nearby buildings and people just by existing. She is ugly without makeup. Unfaithful. Fell in love with Rai at first sight.

An Irish nobleman. Brown hair. A playboy. He is in love with Nikon and believes she is the real one.

An Irish Duke. Guest's former fiancé. Currently engaged to Nikon. A piece of trash who uses his power as a weapon. Black hair. Believes Nikon is the real one. Once he realizes Guest is the real one, he shamelessly tries to propose to her again as if it were only natural.
