Description
One-Eyed Dragon Princess Masamune Date is a Sengoku-era warlord depicted as a young woman with long green hair, yellow eyes, and tanned skin. In her world, she is a feudal lord of notable military standing, but she depends heavily on her talented retainer Kojuro Katakura, who manages the practical matters of her household. Because of this reliance, she is unaccustomed to everyday tasks and possesses a trusting, big-hearted nature that leaves her open to being deceived.

When she is transported to the modern world, she is quickly tricked by members of the yakuza into working as an enforcer. Her sense of honor and her violent temperament make her effective in that role, but her unfamiliarity with modern life and her willingness to take people at face value allow the criminals to exploit her. After being arrested, she manages to escape and take revenge on those who used her.

Her personality combines a strict commitment to honor with a quick temper and a readiness to use force. She cannot tolerate people who act without principles or integrity, and this conviction fuels her anger at having been manipulated. Despite her ferocity, her past dependence on Kojuro reveals a softer and less self-sufficient side, and her time in the modern world forces her to handle situations she once left to others.

Her central motivation is to reunite with Kojuro Katakura, the retainer she relies on, after the two are separated. The search for him gives direction to her journey and serves as an emotional anchor for a character otherwise defined by pride and combat.

Within the anime, she is the focus of the episode titled One-eyed Dragon, which dramatizes her arrival in the present day, her manipulation by the yakuza, and her eventual retaliation. Her most important relationship is with Kojuro, whose competence contrasts with her helplessness in ordinary matters, and her bond with him highlights her struggle to manage without his support.

Her notable abilities are primarily combat-related; she is portrayed as an honorable yet violent warrior who can hold her own in physical confrontations and carry out the enforcer duties imposed on her. The most distinctive traits she displays are the combination of pride, honor, and gullibility that defines her role in the story.
