Ei Sesshou

Ei Sesshou (殺生永, Sesshō Ei) is the main protagonist of The Other Side written and authored by Snow Kanzaki. She's one of the many students to be featured in Assassination Classroom. She had been assigned to be in Korosensei's Class 3-E of Kunugigaoka Junior High School. Ei had been sent out into the field disguised as a transfer student who had later been revealed to be an assassin working part-time.

Appearance
Ei is a young, pale teenager with bright blue ocean eyes and long wavy black hair tied in a two-side-up hairstyle, consisting of twin tails tied with black ribbons, as the majority of her raven locks hang mostly down to her shoulders.

Her casual attire consists of a red turtleneck, a black skirt and long black socks under brown leather flats. When in her school uniform, she wears a white dress shirt accompanied by cufflinks. She's mostly seen sporting this on with a beige colored vest accompanied by a black skirt and stockings with dress shoes. Ei usually accompanies it with a long red coat reaching down to her knees.

As a child, Ei's clothing consisted of a white dress shirt with a red necktie. This also includes a red skirt and long black socks, similar to the exact same style of fashion she wears today.

Seven years after her graduation, Ei has opted to pull down her hair completely. She wears a long sleeved red shirt and a long maroon skirt. Her alternative costume is a long red jacket, a white polo neck jumper, a black mini skirt, and long leather boots to match.

Personality
To the mere age of seven years, Ei was trained in the art of killing and in the art manipulation as well. Due to the excessive training she had to endure as a child, Ei became quite the placid and courteous individual. This demeanor of hers had not always been very well received by her fellow classmates both in and out of Class 3-E as Ei would oftentimes use this to her advantage in order to manipulate others to do her bidding.

Throughout the series, it's been shown that although Ei is a kind person at heart, she's also a naturally blunt person; as shown when she first met Karma and Nagisa.
