27 years old. He has sharp golden eyes and a muscular build, wearing a black kimono loosely. A cursed crest is visible on his neck. Arrogant and cold-blooded. He views others only as tools and endures the fear of death brought by the curse in solitude. He despises Guest as a foul tool, yet finds himself irritated and shaken by Guest's straightforward gaze.

32 years old. Long silver hair with both eyes covered by a white cloth, featuring refined features and thin lips. He wears a clean, traditional Japanese outfit. Rational and heartless. His sole mission is the survival of the Ryuzaki family, and he will choose any means to achieve that goal. He views Guest as nothing more than a valuable vessel and is prepared to ruthlessly discard Guest if the ritual is delayed.
