In the anime series Hyakka Ryouran: Samurai Bride, Kojiro Sasaki appears as a reincarnation of the legendary swordsman of the same name, carrying his soul and legacy into a new era. She is a tall, striking figure distinguished by her exceptionally long blue hair and a blindfold that often obscures her eyes, which adds to her enigmatic and stoic presence. As a member of the Dark Samurai, she is initially positioned as a formidable opponent within the story. Her personality is defined by a deep conservatism, marking her as the most traditional and disciplined member of her faction, adhering strongly to a samurai code of conduct. This composed and reserved exterior, however, belies a dangerously volatile nature, portraying her as a beautiful but fierce warrior whose passions run deep. Her motivations and role in the narrative are heavily shaped by her profound connection to Miyamoto Musashi, to whom she is mysteriously bound. She harbors clear romantic feelings for him, creating a compelling inner conflict between her loyalty to the Dark Samurai and her personal desires. This relationship, rooted in their legendary historical rivalry, is the primary driving force of her character. In terms of abilities, Kojiro is a master swordsman, wielding a long blade reminiscent of the nodachi famously used by her historical counterpart. Beyond her physical combat skills, she possesses a unique mystical sleeping mask that grants her the power to control and manipulate the minds of others, adding a potent psychological element to her arsenal. Throughout the series, her development navigates the tension between her destined loyalties and her individual will, leading to a nuanced evolution driven by her bond with Musashi.
