List of The Disastrous Life of Saiki K. characters

This is a list of characters for the manga and anime series The Disastrous Life of Saiki K..

Saiki family

 * The main character of the series. He is a high school student who was born with all manners of psychic abilities despite having very ordinary biological parents. Because of the misery that comes from the attention he receives as a psychic, Kusuo desires a normal, plain life, purposefully keeping average grades and performance in sports activities. He uses telepathy to read people's minds, and can share this power with others. His other abilities include telekinesis, levitation, x-ray vision, clairvoyance, astral projection, pyrokinesis, mind control, psychometrics, invisibility, and more. He can teleport objects, but has to replace the item with something of equal value. He can also temporarily pick up other psychic abilities, such as Toritsuka's ability to see ghosts, by making physical contact. He has dark pink hair, with two antennae on his head that people think are hair ornaments, but they actually regulate his constantly growing powers that would otherwise go out of control and destroy things as well as cause global catastrophes. He can transform into animals or into a girl that he names Kusuko (Voiced by: Haruka Tomatsu). Kusuo wears glasses so that his gaze does not turn someone to stone. His favorite snack is coffee jelly. He is vulnerable to bugs, especially cockroaches, because he cannot read their minds and predict their actions.
 * His family name is pronounced like psyche and is based on the English word psychic.

After graduating from university, he moves in with his grandparents.

 * A self-proclaimed beautiful girl who is part of Saiki's class. She acts modest in public as that increases her appeal, but secretly loves the attention that is lavished upon her and all the favors that the guys are willing to do for her. She has the favor of the gods when it comes to events of chance. When Saiki does not treat her like a queen bee, and even ignores her, she becomes obsessed with making him react or show admiration, like saying "Oh wow" (おっふ) at her. She has a fan club called the Kokomins. In later chapters, it is revealed that her charisma and beauty does not affect guys who strongly love someone else (Kuniharu), those with pure eyes that view everyone equally (Hairo), or those who can see her true nature (Kusuo and his brother Kusuke). Her one weakness is with little kids such as Yūta who exhibit all three of those characteristics. In one of the chapters, it is shown she harbors a list of things that people should never say to her. Despite being wooed by guys like Metori Saiko that fit her ideal financial expectations, she develops feelings of love for Saiki. In the anime, she is typically coated in a golden glow.
 * Her family name is based on the Japanese wasei-eigo term for telepathy.
