Saiki Kusuo

"MC"

- He should really choose his friends more wisely. This is just some advice from a friend.

Kusuo Saiki (斉木 楠雄 Saiki Kusuo) is the main protagonist of the series who has all kinds of ESP-related abilities. He usually avoids getting into troublesome situations. His trademark appearances contain his green-tinted glasses and two pink antennas located slightly above each ear which have the function of limiting his power. In the beginning, he was always seen alone but as the story progresses he eventually gets along with his schoolmates, especially Riki and Shun.

Appearance
As a child, Kusuo does not wear any limiter and poses a striking Pink hair that differs from both of his parents. In his current image, he has a limiter on the both sides of his head which he never removes unless it is necessary or when it is accidentally removed. During his days at school, he wears the standard PK Academy uniform that all male students wear, while on his days off he wears clothes that are sewn by his mother. Kusuo's appearance however, is not limited to that of a male, as he can also transform into anything (but it takes 2 hours to transform).

In his female form, Kusuo is first known as Kusuko(he later changes it to Kurikou), has lighter Pink hair, and unlike the male form she has no limiter on her head though she still wears glasses. In his cat form, Kusuo is known as Sai and has white fur, he still wears his glasses, and his limiter is in the form of a collar around his neck.

Personality
As a Psi user, Kusuo is usually emotionless and constrains himself from having any friends, preferring to do whatever it takes to not to be associated with others so he doesn't expose his powers. Due to this, he has never spoken using his voice, instead projecting his words via telepathy into the minds of his friends. Although he didn't have any friends during his first year, during his 2nd year, a lot of his classmates like Riki, Shun, Kineshi, Aren, Kokomi, Chiyo, Reita and Mikoto kept on bugging him and somehow changed his perspective. He later thought of himself as a friend of theirs and even called Shun his friend.

Although he doesn't express much interest in many things due to his powers (e.g. surprise parties, romance, fortune-telling, etc), Kusuo is addicted to the dessert known as coffee jello and can be persuaded to participate in anything his friends are in as long as he receives his coffee jello. His addiction is not just limited to coffee jello but also to different kinds of sweets. Despite being able to get anything he wants without using any money, Kusuo uses money and saves up money to buy something he wants, like the Coffee Jelly Maker. His kind mom was the sole reason why he didn't abuse his own psychic abilities for nefarious activities. Kusuo also has an interest in television shows, due to electronics being unaffected by his powers, allowing him to enjoy dramas/scenes that prevent the use of his telepathy which leaves him open to spoilers from the thoughts of others.
