*Kaina Tsutsumi, better known as Lady Nagant, is a minor antagonist in the My Hero Academia franchise. She is a former Pro Hero that seeks to bring the fall of the Pro-Hero society. As a result of killing the Hero Public Safety Commission's chairman, she was imprisoned in Tartarus. Her arrest was covered up, saying that she killed a fellow hero.

Lady Nagant was later freed by All For One, who then hired her as a mercenary to retrieve the current wielder of One For All, Izuku Midoriya, until she was defeated by him. She later helped Midoriya and the heroes against All For One and the Paranormal Liberation Front.

Lady Nagant is a tall woman in her late thirties with short, two-tone hair which is blue with pink highlights and purple eyes. She is remarked to be quite beautiful, as noted by All For One.

Her costume consists of a sleeveless dress, zipped boots and a utility belt that has canisters attached to it, which contain her bullets.

During her career as a Pro-Hero, she had much longer hair which she would tie up in a ponytail whenever she was active on her missions. Her costume was also different. Instead of a dress, she wore what appeared to be an armed suit with various padding on her chest and knees to keep her suit armed and protected.*
