Kanata Mayoi

Kanata Mayoi is a student in Korosensei's Class 3-E of Kunugigaoka Junior High School and a major supporting character of Assassination Classroom.

Appearance
Yūko has a "frail-looking" build and light complexion with long, dark grey hair, and wears bangs, parted twice as to not obscure her vision. She wears her hair loose with long side bangs along with somewhat sharp but empty-looking-grey eyes.

After transferring to Kunugigaoka Junior High School, Kanata received a specialized uniform. Kanata has a loose dark grey sweater with sleeves that stop at her forearms. The rest of her uniform appears to be the usual female uniform. She also often carries her sword on her back.

Personality
When introduced to the series, Kanata was quiet, cynical, and distrustful of others. Though taciturn, she wasn't afraid to tell others what she really thought of them. Impassive and, at times, obtuse, she tends to think only for herself and operates on logic alone, never letting emotion guide her, making her seem completely apathetic and indifferent.

She is also one of the quickest-thinking characters and often analyzes a situation with great ease and accuracy. In spite of her young age, her way of thinking, knowledge, and pragmatism give her the attitude of an adult.

Abilities
Overall Abilities: As a child prodigy, Kanata is a very powerful swordsman and combatant. She is noted to be incredibly talented despite her young age.

Enhanced Vision: Yūko possesses extremely sharp eyesight, being able to accurately predict her opponent's next attack and movements by simply observing the subtle shifts of their muscles, joints and the slight movements of their eyes. This allows her to make effective counterattacks and dodges and stay ahead of her opponents.

Great Intellect: As a child prodigy, Kanata is extremely intelligent. Despite not speaking for most of her childhood, her first words were very clear and pronounced. Kanata has showcased a high level of tactical thinking. She is capable of quickly spotting various weaknesses her opponents may have, and has a good grasp on all aspects of the world. She can stay one step of her opponent in battle and can read other people's moves through their personalities. When it came to her assignments, Kanata approached her missions with careful calculation, caution, and patience.

Master Weapons Specialist: Able to wield a wide assortment of different weapons, Kanata is considered to be an expert in all sorts of weaponry. She normally uses katanas in battle but is fully capable of switching between multiple weapons in the course of a single fight. She is also fully capable of incorporating martial arts such as aikido into close range combat. Even now, Kanata continues to wield her katana as her main weapon. She is far more proficient and moves extremely well as a swordsman.

Extrasensory Perception: Kanata has extremely honed senses able to pick up things outside the normal range of perception, such as discerning the aura of an ally from a foe.

Immense Speed & Reflexes: Kanata has been noted on several occasions to have superhuman speed, so much so that its impossible for her opponents to read her moves. As an assassin, Kanata is tremendously fast, displaying the ability to blitz opponents and move in bursts of speeds akin to teleporting. Kanata has attained incredible physical strength through harsh training. She can jump extremely high distances incredibly fast, showing her incredible leg strength. In terms of arm strength, she can swing her katana at subsonic speeds incessantly without tiring.
