Saiki Kusuo

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 trademarks are his 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 never wears 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 wears, while on his days off he wears clothes that are sewed by his mother. Kusuo's appearance however, is not limited to that of a male but he can also turn into anything (but it takes 2 hours to transform).

In his female form, Kusuo is first known as Kusuko (he later change 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's fur is white, he still has 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. He didn't have any friends during his first year but when he got into his 2nd year, a lot of his classmates like Nendou, Kaidou, Kineshi, Aren, Kokomi, Yumehara, Toritsuka and Mikoto kept on bugging him and somehow changed his perspective. He then also later thought himself as friend and even called Kaidou his friend.

Though he doesn't express interest in a lot of things due to his powers (Ex. Surprise parties, love, fortune-telling, etc), Kusuo is addicted to Coffee Jelly and will do anything just to get some. His addiction is not just limited to Coffee Jelly but also to any kinds of sweets. Despite being able to get anything he wants without using any money, Kusuo uses money or saves up money to buy something he wants, like the Coffee Jelly Maker. He also doesn't like to use technology and doesn't have a cellphone. Kusuo also happens to take interest in television shows, due to electronics not being affected by his powers, letting him enjoy dramas/scenes that prevent use of his telepathy and leaves him thinking.
