All Characters In The Disastrous Life of Saiki K.

Saiki family Characters

Kusuo Saiki

He is a high school student who was born with all psychic abilities despite having very ordinary parents. Because of the misery that comes from the attention he receives as a psychic, Kusuo desires a normal life, keeping average grades and performance in sports activities. He uses telepathy to read people's minds, but he shares telepathy with others. His other abilities include telekinesis, levitation, x-ray vision, clairvoyance, astral projection, pyrokinesis, mind control, psychometrics, and invisibility. He can teleport things but has to replace the item with something of equal value. 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 Kuriko. Kusuo wears glasses so that his gaze doesn't 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.

Kuniharu Saiki

Kusuo's father, who has to suck up to his employers so much that he has gained a taste for licking shoes. He works as an editor for a manga publishing company that appears to be a knock-off of Shueisha.

Kurumi Saiki

Kusuo's mother whom he states is "the one who keep him from turning into dark side" because of her kindness, but can be scary when needed that Kusuo won't be able to defy her. She is allergic to cats. Her maiden name is also Saiki. She can be rather naive and air-headed at times.

Kusuo's Grandparents

Kumagoro Saiki and Kumi Saiki are Kusuo's grandparents. Kumagoro has a classic tsundere personality, that is, he is hard on the outside, but soft on the inside. He is very fond of his daughter, but dislikes his son-in-law, often beating him up or sending him away to run errands. He wants to get to know his grandson better. Kumi acts fairly young for her age, with her choice of fashionable clothes and her gyaru (gal) speech.

Kusuke Saiki

Kusuo's older brother. He is a super genius who invents devices and machines, but lacks psychic abilities and thus always loses in any sort of competition with his brother. When he was 14, he moved to England where he has been a doctoral candidate at Cambridge University. He invents a "telepathy canceler" so that Kusuo cannot read his thoughts. After graduating from university, he moves in with his grandparents.

PK Academy Characters

Riki Nendo

Nendo is a muscular student with a Mohawk hairstyle, a scar over his left eye, and a cleft chin. He is the only student at PK Academy whose mind Saiki cannot read, simply because he is dumb. As such, Saiki often fears his overly friendly and carefree nature as he cannot predict his actions. However, Nendo is fond of Saiki and considers him his best buddy. His family members have the same faces as him, with his late father with a scar over his right eye instead of Riki's left, and his mother Midori with scars over both eyes. He has a horrible singing voice.

Shun Kaido

A classmate who calls himself "The Jet-Black Wings", thinking he is secretly living in a fantasy world ruled by an evil organization called Dark Reunion. Although he is still attached to his delusional mind, he slowly builds a normal relationship with his schoolmates despite his chūnibyō antics popping up. His mother is very strict on his school work. Kaido has low physical stamina and strength. He also has no sense of direction. He has a younger sister who is fairly serious, and a little brother who idolizes him.

Kineshi Hairo

Saiki's class representative is an overly hot-blooded, energetic, passionate student who enjoys sports and is constantly trying to get other people motivated. He has bright red hair and typically wears a nasal strip. According to Saiki, as hard as he is on others, he is even harder on himself. Due to his nature, he is well-trusted by his classmates. A running gag is that whenever he trips his shorts drop and his butt is exposed.

Kokomi Teruhashi

Teruhashi is 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 that and even ignores her, she becomes obsessed with making him react or show admiration, like saying "Oh wow" at her. She has a fan club called the Kokomins. It is revealed that her charisma does not affect guys who strongly love someone else, those with pure eyes that view everyone equally, or those who can see her true nature. Her one weakness is with little kids 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. She is typically bathed in a bright yellow glow.

Chiyo Yumehara

Chiyo is Saiki's classmate who has a romanticized perspective on relationships despite having a history of poor choices of boyfriends. She has short brown hair and wears a hairband. After failing to attract Saiki with her romantic encounters, she dates the sweet-talking Takeru, but breaks up with him after she realizes he uses the same pick-up lines and other annoying habits. Chiyo becomes friends with Kokomi, but suspects they both have crushes on Saiki. Her attention is diverted to Shun Kaido, who saves her from being further belittled by some guys at the beach during the school trip, but who is oblivious that he is even in a relationship with her. She joins the Occult Club because of him and becomes friends with Arisa where they dabble mostly in girl talk about relationships. After a Valentine's Day misunderstanding, she and Shun agree to remain friends instead of advancing the relationship. Chiyo is the subject of some side stories involving weight loss and obesity.

Reita Toritsuka

Toritsuka is a medium and one of three people outside of Saiki's family to know of Saiki's abilities. He has the ability to see spirits, but is only interested in using his ability to attract girls and to become rich. His guardian ghost is Nendo's late father. He later lets other spirits possess his body. Toritsuka starts an Occult Club at school. He works as an assistant at the temple. Aiura, Toritsuka, and Saiki constitute the "Psychic Trio" at PK Academy.

Imu become too attached to Kokomi when she sees that Kokomi has struggles in her relating to Saiki. But she was afraid that her attachment, which could go beyond in combination with beauty of Kokomi will drive to end up going to a different world. For this reason, she wanted to find a boyfriend. When she saw Kokomi’s brother, she was falling in love with him and becoming his fan.

Mikoto Aiura

Aiura is a gyaru with lime-blonde hair, tan skin, and big breasts who transfers to Saiki's class. She is a fortune teller who can read the future and determine someone's love compatibility, often accompanied with spontaneous gestures and movements that she makes up to get her in the mood. Saiki realizes her powers are for real after she accurately assesses his classmates. Her goal is to find her true love, and starts becoming interested in Kusuo but dislikes Toritsuka. She can read people's auras, although Saiki's aura is so intense that she cannot read his.
