Kuro-Sensei

Kuro is a surreal alien, capable of moving faster than the speed of light and possessing incredible strength, having destroyed half of the moon (70%).

Korosensei has the appearance of a yellow octopus about three meters tall, with a large, bulbous head bearing a wide grin that rarely fades or moves, and small, piercing eyes. He uses two tentacles as arms, each with two antennae-like fingers, and utilizes the rest of his seemingly gelatinous limbs – his tentacles – to walk. Korosensei has a pair of hidden nostrils, which gives him the impression of having four eyes if detected. Due to his constant grin, he changes color to express his emotions.

Korosensei wears a black graduation gown, a small square black graduation cap with a yellow tassel, and a large black tie with a yellow crescent moon, a gift from Aguri Yukimura.

As a human, he had pale skin, a slender build, dark eyes, and short black hair that reached the nape of his neck. He sported a friendly smile, which he initially used to manipulate others. When committing assassinations, he wore formal attire. After being taken prisoner by Kotaro Yanagisawa, he was placed in a patient's uniform until his escape and transformation.

It was revealed that he was raised in an environment "where everyone could easily betray each other, to the point where you could only trust yourself." Amidst these difficulties, he decided to become an assassin to survive. Although he had an apprentice, he saw him only as a tool for his own purposes, which led the apprentice to ultimately betray his master.

However, after meeting Aguri Yukimura, he finally learned what true compassion was, becoming much kinder as a result. According to Aguri, if he had been born in a peaceful country, he would be "a little lecherous, clever, clumsy, somewhat petty and stubborn" and would smile because he is genuinely a kind person. [3] This prediction ended up reflecting his personality, which became evident after he responded to the tentacles.

In his first appearance, Korosensei was an optimistic individual who made absurd and seemingly banal requests, despite claiming that he would cause the destruction of the planet within a year. He was also quite kind to others in general and could switch between a silly, childish tone and a serious one in an instant. According to Nagisa Shiota, Korosensei was also sometimes unintentionally petty with others and loved to gossip, two characteristics quite present throughout the series.
