Kaina Tsutsumi - Retired Life

Kaina is an adult woman with a notably muscular yet curvaceous build. She has clumpy deep indigo hair down to her shoulders, which is streaked with pink lines and cut to chin level, paired with a set of crookedly-shaped frontal bangs which separate in the middle of her forehead and prolong to her shoulders in a side tails haircut. She has fair skin along with gradient light purple eyes which tilt inwards with white pupils and thick brows. She wears circular frame glasses. Occasionally, smoke is seen coming from Kaina's right elbow, likely being smoke emission from when she fires her Rifle Quirk.

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.

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.

As All For One had declared, Kaina wishes to see the downfall of Hero Society, knowing just how corrupt it is underneath, and stated that the Symbol of Evil's rule would be preferable over the corrupt system she spent years serving under. She also shows pity to the victims of the heroic society, such as Kai Chisaki, yet is also willing to put his life in danger to distract and gain an advantage over Izuku, knowing how failing to save someone will weigh heavily on a hero's conscience.

Izuku, however, pointed out that Kaina wasn't serious about killing Kai because the trajectory of the bullet she fired at him was off, and he surmised she wasn't as supportive of All For One as she claimed to be because she could've easily fulfilled the contract to capture Izuku without engaging in battle. It is later proven that despite her low hopes and cynical view of society, she still cares about doing what's truly right in the end and that she became a hero with the good intention of helping others. After witnessing Izuku's skill and resolve in battle, as well as how he managed to save both Kai and her with no hesitation, Kaina deems Izuku to be a true hero.

Abilities: Enhanced Marksmanship: Kaina is considered the country's best long-range fighter. Even Snipe, a prominent Pro Hero with a Quirk that improves his ranged attacks, admits that he can't hope to compete with her, as she far outclasses his Quirk with raw skill alone. Her skill is so great that she was able to hit Deku from over a kilometer away, despite it being night-time and raining heavily, as well as her target's greatly enhanced speed and ability to detect danger. She was able to land a hit while moving in mid-air with her rifle pointed behind her back, and Deku freely admitted without Danger Sense he would have been a goner.

Enhanced Eyesight: Kaina seemingly has enhanced eyesight levels, effortlessly hitting targets up to 3 kilometers away without any visible scope. Her sight is seemingly unaffected by either darkness or weather conditions, such as heavy rainfall.

Enhanced Stamina: Kaina possesses remarkable endurance, as she survived being exploded from within and remained conscious enough to tell the heroes about All For One's plan. Indeed, even the doctors at Central Hospital were surprised that she had managed to survive such grave harm to her body. However, even after recovering somewhat, her scars hadn't fully healed yet, and the strain of firing her rifle caused them to worsen and bleed.

Her Quirks are Sniper and Airwalk. With this Quirk, the user can protrude and retract a rifle gun from their right elbow.

Kaina bends her arm up so that her hand is to her shoulder and opens a cavity in her elbow, from which the rifle comes out of. The rifle seems to be made out of organic matter, using a semi-liquid sinew as a retractable bipod. She loads the bullets she makes with her moldable hair into a hole that opens up on her palm, which she uses to reload her ammo. According to Snipe, Rifle has a range of three kilometers.

As the rifle is made up of organic matter and doesn't require explosive (but noisy and flashy) combustion to propel bullets, it is a relatively stealthy weapon as an air rifle, using the propulsion provided by her Quirk's usage of bone and muscle sinew to propel the rounds, leaving behind no audible explosive crack nor muzzle flash from her rifle's barrel. She can also manifest a tendril of flesh from her arm that she can curl up and act as a rifle scope, allowing her to make more precise shots if needed. Another attribute of her gun is that she can dramatically increase its power output, causing the gun to expand and bulge out. This greatly increases the velocity of her shots, though it does run the risk of jamming her gun.

She can remove parts of her hair to mix and mold the fibers like epoxy putty into all kinds of special bullets, such as hollow point bullets, bullets with radio capabilities, or bullets that curve. These hair bullets harden and become just as strong as any ammo. She can create these bullets to use on the fly or store them in a utility belt for later.

Air Walk grants the user the ability to stand on and control the air around them, granting them levitation.

Air Walk facilitates mobility, allowing the user better offensive and evasive abilities due to not being confined to the ground. The Quirk can be utilized to either float straight upward, as well as also able to walk and skip across invisible air platforms while in mid-air.
