Kaina Tsusumi

Kaina is a serious and disciplined woman who does not hesitate to hurt people to fulfill her mission or achieve her goals. She is direct and ruthless toward her adversaries, firing a warning shot at Izuku and threatening to dismember the young hero should he not come quietly. Outside of her stoic and cold-blooded attitude however, Kaina has a more casual and happier side that she shows on occasion. She proves to be quite fearless, not being intimidated upon being approached by All For One and even remarking over how she targeted him in the past.

Lady Nagant after committing a murder Kaina having been trained to kill under the Commission's orders. In the past, Kaina had an optimistic outlook in her desire to be a great hero but was led down a dark path by her superiors, having been trained to kill villains and corrupt heroes, sometimes unjustly, who were threatening to disrupt the order in society. She assassinated criminals who the Hero Public Safety Commission wanted to have "disappear" rather than be handled by the proper legal process. Kaina's repeated killings made her disillusioned, and she soon fell into a depressive state upon realizing that the Hero Commission maintains a fragile and hollow peace at the expense of others while hypocritically justifying that their actions are for the good of everyone. Upon seeing some young children in admiration over her, Kaina eventually reached her breaking point, realizing that the youth of society wholly admire Heroes and wish to become them while not being aware of the bloodshed behind the scenes. While reaching out to shake the hands of said children, she saw how bloodied her hand was and retracted it in horror, not wanting to pass said bloodshed on to them. Upon implying that she wished to leave her post, and receiving a veiled threat to her life in response, Kaina finally snapped and killed her superior. Rifle: Kaina's Quirk allows her to extend a rifle from her right elbow. She loads bullets into the rifle through a hole in her palm. Her firing range is 3 kilometers. Additionally, she can increase the velocity of her shots by dramatically increasing the rifles power output, causing the gun barrel to expand and bulge out, though this does risk the gun jamming.

She can also extend a tendril from her rifle that she can curl up to form a scope.

Rifle also allows her to pluck strands of her bi-colored hair, which she can twist and mold like Epoxy putty and harden to create various types of bullets (such as hollow-point bullets and curving bullets) that are as strong as any ammo. These hair bullets are capable of recording her voice and replaying the message after they hit.

Air Walk: Kaina's second Quirk allows her to levitate and jump in mid-air. She primarily uses this Quirk in tandem with her Rifle Quirk, allowing her to quickly change sniping positions and chase after her target, greatly expanding the range of her shots. Kaina received this Quirk from All For One, who gave it to her as a form of payment for going after Izuku.
