Maki Hojo plays Yukiko Urayama, an ordinary woman who dreams of a quiet life and marrying her fiancé, Shotaro Sakae. However, the Sakae family harbors a dark, generations-old tradition: binding their brides in elaborate, inescapable restraints. This secret ritual, long upheld by the family, is far more than mere custom—it carries a profound and sinister significance that will irrevocably alter Yukiko's life. Under the watchful eyes of Attackers and the Dragon Bondage label, the ceremony unfolds into a harrowing tale of humiliation, tight bondage, and violation, as Yukiko is stripped of her autonomy and subjected to the family's brutal rites.
