Kusuke Saiki (Japanese: 斉さい木き　空くう助すけ , Hepburn: Saiki Kūsuke) is the main antagonist of Saiki Kusuo no Ψ Nan. He is the eldest son of Kuniharu and Kurumi, and the older brother of Kusuo. He is a super genius who likes to invent machines/devices, and he's two years older than Kusuo.
Kusuke, like Kusuo, was born with a different hair colour to his parents. He has blond hair and dark green eyes. He wears his "Telepathy Canceller" whenever he is around Kusuo, but due to his intellect he still somehow knows what Kusuo is trying to say. When working he is mostly seen with his machines, wearing a typical white lab coat worn by scientists. When in university, he wears a long black robe with a white collar buttoned up, and on his days off, he wears normal clothes such as a t-shirt and pants.

Kusuke is prideful and competitive when it comes to Kusuo. He would have done anything to win against him when they were kids. However, he would always lose against his little brother. Thus, he became addicted to playing/fighting with Kusuo. Kusuke can come off as sadistic, such as when he enjoyed seeing Kusuo, Shun and Riki being chased by crowds of people in London, but on the other hand he is obsessed with losing to Kusuo, to the point that he receives an unreasonable amount of pleasure from it at the end of that run of chapters.
Despite Kusuke's competitive nature, he still is caring to Kusuo and his mother. This is best shown when he made a time machine to go back 20 years in the past when Kusuo was still alive (in that chapter, they were in a parallel universe where Kusuo had died.) He won't frame family for something they haven't done, and most of his competitions with Kusuo are just teasing. His father is an exception to this for some reason.

Kusuo always thought his older brother hated him, but Kusuke cleared this up and told Kusuo that he only liked to tease him.
Kusuke is often deceitful, always showing an angelic smile towards their parents despite thinking ill of everyone, although just like Kusuo he disrespects his father outwardly. Like his brother, he doesn't appear interested in love, as he showed himself immune to the beauty of Kokomi and made her cry by bluntly telling her that she was not fit for Kusuo, although it was swiftly revealed that Kokomi was using Angel Tears. She summoned every man in the vicinity and Kusuke had to summon a helicopter to escape.
When something or someone catched his attention he becomes obsessed with it

Kusuke was born on the 16th of June to Saiki Kurumi and Saiki Kuniharu. At 1 month old, he spoke his first words and quickly was able to communicate with his parents. He then was able to write and do mathematics at the age of 2. Not long afterwards, his younger brother, Saiki Kusuo, was born, and it quickly became apparent that he was a psychic. Kusuke developed a complex from this, always trying to compete with his younger brother, only to lose every single time.

Sometime in middle school he, along with Kusuo, created the control devices that Kusuo wears. At the age of 14, he left for England and studied in Cambridge, getting a masters and PhD.
He has an IQ of 218.
Like his brother, he doesn't seem interested in love, as he was immune to Kokomi's beauty and quite brusque when speaking to her.

Chaotic Evil (Kusuke is obsessed with competing against his brother Kusuo, showing a desire to win at any cost. He enjoys watching Kusuo and his friends in difficult and dangerous situations. Kusuke is obsessed with Kusuo and acts selfishly to get attention, such as when he builds a time machine or makes Kokomi cry.)

Kusuo Saiki (Japanese: 斉さい木き　楠くす雄お, Hepburn: Saiki Kusuo) is the main protagonist of Saiki Kusuo no Ψ Nan who has all kinds of psychic related abilities. He usually tries to avoid getting involved in problematic or attention-grabbing situations, but his attempts always end up going wrong or having unusual ends to his displeasure. His trademark appearance contains his constant frown, his green-tinted glasses and two pink antennas located slightly above each ear, which have the function of limiting his power. Initially he was always seen alone, but in the course of the story he develops lasting friendships with his classmates and schoolmates, especially with Riki Nendou and Shun Kaido, or with his neighbors like Yuuta Iridatsu. Kusuo was starred by Kento Yamazaki in the live action movie based on the series.
Kusuo has an average build and height. He has short hot pink hair, fair skin, and pale purple eyes with no signs of pupils nor emotion. Kusuo wears a pair of controller devices, one on each side of his head, which are never removed except in situations of absolute necessity or by accident. The devices resemble white, cyan antennae, with pink, lollipop-like spheres. Accompanying the devices, Kusuo wears white glasses with lime green lenses to prevent his petrification power. During the days he has school, he wears the standard PK Academy uniform that all male students wear. On his days off from school, he occasionally wears clothes that are sewn by his mother. However, there are times he is forced to buy clothes since his mother has an exotic taste in clothing patterns.

Kusuo's physical appearance is unlimited, since he can transform himself into any other living being, but each transformation has a 2-hour interval. While in his female/genderswap form, Kusuo goes under the name Kuriko[6] (formerly Kusuko). In this form, he has lighter pink hair (slightly larger), lacks visible limiters, wears clear glasses, and is usually wearing the female standard PK Academy uniform. In his cat form, Kusuo is known as Psi/Sai and has white fur. In this form, he still wears his glasses and his limiter is in the form of a collar around his neck.
As a child, depending on the time period, Kusuo does not wear any limiters nor his glasses, showing his pale purple eyes. He has always had his striking hot pink hair, that differs from both of his parents and the rest of the world, until he used mind control.

As of the finale, he no longer wears his limiters or glasses. However, right in the end of the epilogue chapters, he reprises them due to his powers begin to return.

Personality:
As the main character and the story is nearly driven by his narrative, Kusuo is a fully rounded character that changes over the course of the series.
When Kusuo was a child, he was more open to his emotions. Part of it was due to the fact that he was unaware of what his powers did, such as breaking a whack-a-mole machine in an arcade and thinking the machine was giving him praise. He was highly mischievous, such as making his parents look for him for 5 hours after he teleported, and smiled around others without a second thought. However over the course of time, with having to hide his psychic powers from others and his abilities slowly ruining experiences for him, he started to close himself up.
Thus, in the present, Kusuo is a reticent, self-centered, reclusive shut-in who hates being the center of attention, he is quite reserved and rarely uses his voice, instead preferring to project his words via telepathy into the minds of others. To avoid interactions, he tries to make other people disinterested in him or avoid others as much as possible. For example, Kusuo hiding from the other characters in the bathroom and Kusuo talking to Imu, knowing Kokomi would not like it. Despite this, Kusuo is very adept at determining what people want and executing plans based on them. He was able to single-handedly raise Chiyo's favorability of Takeru from 54 to 95, and to raise Reita's of Arisu to 98 on a whim.

Despite being completely anti-social, Kusuo is more than capable of making selfless choices, willing to sacrifice his own happiness for the sake of others. He gave up his coffee jelly to get a baseball back to a child, gave Chisato a plane ticket to Okinawa knowing that it will lead to Kokomi winning her way, and preferring to let his father be him, himself being left alone, just so he does not ruin the fun for the other characters. Due in part to this trait, he hates burdening others or owing favors. He always helps Kineshi after he helps him and was visibly disappointed in himself for making his mother keep his abilities a secret. Kusuo is also careful to never disrespect or insult his acquaintances in their faces. With these characteristics, coupled with his reserved nature, those that know him well, and even Kusuo himself, consider him a tsundere.
Kusuo is one of the most responsible characters in the series. He helps with chores around the house, such as cleaning and buying groceries. Despite being able to get anything he wants without using any money, Kusuo saves up money to buy the things he wants, like the Coffee Jelly Maker. He is capable of cheating in exams to get a good score, but he decides to get average scores to avoid attention. He also protects the other students' privacy and wellbeing. Most of all, he tries heavily to not rely on his powers, wanting to achieve things for himself.
In spite of his kind-hearted nature, Kusuo does have some faults. While he is quite intelligent, he lacks some common sense on some concepts, especially when it involves social boundaries and the internet. For example, he nearly got scammed by an online shop, believing an item would be cheap and not checking for delivery details. He can easily be manipulated with any sweets, especially coffee jelly. He likes to pry on the other characters, though it is often for their own good; for example, while he has stated that he personally does not think he will not fall in love

Although he doesn’t believe he will ever fall in love, Aiura Mikoto, a soothsayer, has predicted that they are soulmates. Kusuo is also prideful, such as being irritated at the thought of being pickpocketed as he is an esper, describing how incredible his own powers are throughout the series and sometimes referring himself as a god. Not to mention, he is stubborn, such as the case when he refused to admit his obvious seasickness. Despite this, Kusuo is very good at listening to other people, and accepting that he is wrong when the evidence is very clearly against him; his pride doesn't get to his head. Other flawed characteristics include being somewhat pessimistic.
As time progresses, he grows from not having any friends in his first year of high school, having no single thought of becoming close to anyone, to later thinking of himself as a friend of several of his classmates after so much nearly endless pestering from Riki, Shun, Kineshi, Kokomi, Chiyo, Reita, Aren and Mikoto. He always takes care of them when they are in trouble and vice versa. He trusts them enough to nearly tell them about his psychic powers but ultimately did not, just so he will not burden them with a big secret.
Due to a combination of his introverted nature and his subconscious ability to read minds, Kusuo holds little interest in social activities. Therefore, he typically spends his free time alone; he is a bookworm, having several books in his room, and is frequently in his school's library. He enjoys watching television, including anime, due to electronics (unless he uses his psychometry) being mostly unaffected by his powers. While not being able to set foot in a movie theater without getting spoilers, he also enjoys watching movies.

History
Kusuo was born on August 16th by completely normal parents, housewife Kurumi Saiki and manga editor Kuniharu Saiki. He is raised by them alongside with his older brother, Kusuke Saiki.
During his mother's pregnancy with him, Kusuo was using his transformation ability which can be seen in the CT scans. When he was born in the hospital, he came out as a girl but an hour later he became a boy. Exactly 2 weeks after his birth, he spoke his first words to his parents via telepathy. At 1 month, he started to walk and fly. At 1 year old, he was able to run errands. He enters Kindergarten, where he played rock paper scissors and always won against other children and his teachers. After a teacher got angered from losing and unsuccessfully attempted to punch him, rumors started to spread throughout TV and the internet about him. Possibly due to this, at the age of 4, Kusuo was then pursued by a certain nation’s intelligence agency and he ended up erasing the entire nation. After much effort to resolve matters, Kusuo decided to hide his abilities to avoid trouble; Kusuo always being wary on using his abilities when others are possibly around and distancing himself from classmates.
When he was 6 years old, he slowly started to befriended Touma Asumi, an observant boy who retorts to one of their classmates.

Prior to current Kusuo travelling back in time, Touma quickly wakes up and asks young Kusuo if he just healed him and if he is a psychic. Kusuo uses his "playing dumb face" while several other kids were around. The other kids leave but Touma sticks around, still amazed at what he has done. Kusuo takes a liking to him; Touma asks him to show him more and thus he tells Touma about his powers. After some events, Touma ends up telling the class he is a psychic and Kusuo ended up destroying the classroom. Kusuo then swore to himself to never reveal his powers to anyone after that.
After current Kusuo traveled back in time, he influenced the event and everything changed. Young Kusuo leaves before Touma wakes up and unknowingly dropped his name tag. The next day, in PE class, Touma was bullied in front of his classmates. Right before he was about to be hit again, Kusuo uses his powers to their classmate on the pull up bar. At that moment Touma loudly exclaimed that Kusuo is a psychic but Kusuo just uses his "playing dumb face," to deter him.

A year after the pull up bar incident, Touma still talks to Kusuo. They do small talk, such as talking about an art project. Kusuo made a robot for the project, which he later uses to destroy Kusuke’s own robot. Touma thought it was trash but quickly apologizes to him. Touma is soon bullied by their classmates but Kusuo only watches others help him. It became an occurrence where Kusuo sees him get bullied, such as classmates taking his shoes and writing mean things about him in the chalkboard, but does not help him in fear of Touma finding about his abilities. Then one day, Kusuo was walking home when he suddenly heard Touma was in trouble. He runs back to the school and finds that Touma has been knocked out by his classmates and is been made fun of. Kusuo snaps and destroyed the classroom. The next scene shows the destruction of the classroom and the bodies of injured children on the ground with Kusuo standing with a stolid face. He erases their memories of him arriving to the scene and made Touma forget about the pull up bar event. Kusuo soon transfers away, afraid that their memories will come back if he stays.
Sometime closely afterwards, Kusuo started wearing his green-tinted glasses, that he found in his toy box. The glasses block his petrification ability, that grew too much. They are shown when he and the rest of his family visited his maternal grandparents. He got along well with his grandparents in the trip, but neither him nor his parents told them about his powers.

When he was 11 years old, he started wearing his control devices that he and mostly Kusuke invented. They, along with their parents, initially thought it would completely remove his powers. However, the devices instead weaken his powers, to the point of removing his petrification ability for a brief, undisclosed, period of time. Kusuo quickly figured out that his left device limits his powers but did not understand what his right one did. He soon finds out Kusuke put it as a self destruct switch, which, upon removed, his powers were to be revealed to the whole world. Kusuke made it a competition between the two, where he would try to remove it over the years. Kusuo ended up beating him up every time he attempted to grab it. Eventually, about a year later, Kusuke leaves to England and Kusuo does not see him for several years.
Kusuo and his family lived in a different area in Japan up until he was in middle school. Around Kusuo’s first year of high school, the family needed to move after Kusuo caused another accident with his abilities. His parents ended up buying a house from Kusuke located in Hidari Wakibara and moved in. Thus, at 15 years old, Kusuo transfers into PK Academy.

Kurumi Saiki (斉木 久留美, さいき くるみ lit. Saiki Kurumi) is the mother of Kusuo and Kusuke and the wife of Saiki Kuniharu.
Kurumi is considerably younger looking for her age (37 years old) like her mother Saiki Kumi and has a kindly appearance. She sports dark purple eyes and short black hair that is styled exactly like Kusuo's, the only difference being that her hair is slightly longer. In the one-shot volume of the series, she sported long black hair which reached her waist and was tied into a ponytail with a ribbon.
Kurumi is a kind and gentle mother who, according to Kusuo, was one of the prominent reasons why he hasn't done bad things using his psychic powers. She is also very trusting of and never doubts other people. However, when driven pushed her limits, Kurumi becomes scary and hunts down anyone who threaten her family. She loves her family a great deal.

As mentioned by her mother and her son, she is unable to keep secrets. This was seen when she has occasional slip ups of Kusuo's abilities and sheepishly tries to cover up, forcing Kusuo to have alter memories of those who heard it. She would apologize because of her excitement of discussing her son.

Kurumi was born on May 14 and was raised by Saiki Kumi and Saiki Kumagoro.

On November 22, 1994, she was being harassed by Takeuchi Riki, and Kuniharu somehow knocks him unconscious. It was love at first sight, Kuniharu asks for her name only to find out they both have the same last name. They get married on the exact day a year later.

Nearly a year later, her first son, Kusuke, is born. A couple of years afterwards, her second son, Kusuo, is born. She raises them, along with her husband, and did well as both of her sons care for her. A year prior to the start of the series, her and Kuniharu have a fight over coffee jelly but make up soon afterwards.

After meeting her husband Saiki Kuniharu, they got married a year later on the same day.
She is allergic to cats.
Kurumi has a habit of hiding her thumbs whenever she's lying, as stated by Kumi.
Her maiden name is the same as her married name.
During one of Saiki Kurumi's lover's quarrel with Kuniharu, it resulted on Kusuo finding out that both has the same level of love for each other with a result of 38,689 in Kusuo's affection meter.
She never had mom friends until befriending Mrs. Kaidou and Nendou Midori.

Kuniharu Saiki(Japanese: 斉さい木き　國くに春はる , Hepburn: Saiki Kuniharu) is the father of Kusuo and Kusuke and the husband of Kurumi. Kuniharu is one of the supporting characters of the series
Kuniharu often wears a suit and tie when going to work. He sports a pair of glasses and has brown hair and eyes, a change from his first appearance in the one-shot volume of the series where he has black hair and eyes.
Kuniharu is unreliable, reckless and slovenly. He is a doormat who is always nice and respectful to people no matter how rude or scornful they are to him, such as his boss, who orders him to lick his shoes, and his father-in-law, who harbors a strong hatred towards him. His submissive behaviour even borders on making him self-serving, often begging with disgusting teary faces towards his son.

He is not as talented in his profession as he considers himself to be and his ideas often lead to disaster, such as when he becomes the editor for Silent Cyborg (SiCy for short) and his ideas lead the story's ratings to drop down dramatically in the 3 weeks after he starts working with his client. His meetings with his clients usually end with them distraught and depressed, but Kuniharu is prone to denial and remains optimistic of the stories' success, even though he is usually responsible for their downfall.

He is not very good at lying and making up stories, as shown when Nendou turns to stone and Kuniharu tells Nendou’s mother that he must have gone to the washroom—only to be informed by Kusuo that they are in the washroom.

He works as a manga editor. His special skill is flattering his boss. His father (paternal grandfather of Kusuo and Kusuke) has passed away while his mother (paternal grandmother of Kusuo and Kusuke) lives in a family house.
After meeting his wife Saiki Kurumi on November 22, they got married a year later on the same day.
He unknowingly met Nendou’s father in the past and he is part of the reason how he met his wife.
He has hay fever.
He mentions that his mother is still alive while his father is deceased.
One of Kuniharu’s lover's quarrels with Kurumi results in Kusuo finding out that both have the same level of love for each other: 38,689 on Kusuo's affection meter.

Kokomi is a slim girl of average height with a pale complexion. She has long, dark blue hair that flows past her shoulders, with bangs framing her face. Her eyes are round and blue with a downward slant. A golden, occasionally rainbow, aura surrounds her most of the time. Kokomi is considered very attractive, being the most beautiful girl in the world.
When out of town, Kokomi wears feminine clothing, often paired with a pink scarf. On school days, she wears the standard female PK student uniform: a white Seifuku school uniform with a teal sailor collar, white collar flap, and black sleeve cuffs striped with one white line. She pairs this with a light red ribbon tied in a large bow at her collar and a short, pleated teal skirt. Her legwear consists of black socks just below the knee and brown penny loafers.
Kokomi was born as the cutest baby in the world and had very short hair until she was a young child. She wore a pink jumpsuit and held a white bunny stuffed toy in the anime.

In elementary school, Kokomi’s hair reached her shoulders. Her uniform consisted of a bright orange hat, a short long-sleeved teal dress, and navy socks below her knees. She also carried a randoseru, a red leather backpack containing her school supplies.

By middle school, Kokomi’s hair grew just past her shoulders. In the anime, she wore a white blouse, a short pleated navy skirt, and white socks below her knees. In the manga, however, her socks and blouse were dark and long-sleeved. With this, she carried a black handbag.

Kokomi's beauty allows her to easily manipulate situations to her advantage, thanks to her talent for acting. For example, when her class play is in trouble due to a low budget, she uses her beauty and acting skills to create an illusion for the audience. With the help of Kusuo's hypnosis, she makes it seem like they are actually in the story, causing the play to be a success.

Kokomi has a strong willpower, working hard to maintain her reputation as the perfect, beautiful girl. She is careful not to harm others' feelings and treats everybody in a friendly and polite manner. Moreover, she hides her true emotions, such as anger and disappointment, with a smile. However, she occasionally lets them out due to shock or embarrassment. For instance, when someone assumes the person she likes is Nendō Riki, she is appalled and unintentionally yells at him. When given food she dislikes, she eats it because "a perfect beautiful girl never wastes food." Even though all she needs to do is say she doesn't know, she puts in the extra effort for everyone to like her even more. She didn't sleep for several days to remember everything about everyone, causing her to collapse in front of them.
Kokomi's personality changes throughout the series. She initially pursued wealth but later rejected a marriage proposal from Saiko Metori, a famous and wealthy student, and abandoned a life of luxury. She couldn't forgive him for disrespecting her friends and the person she cared about, admitting that she would have accepted immediately if he had proposed earlier. At first, she was frustrated that Kusuo didn't react the way she wanted him to and tried getting back at him. However, over time, she found herself constantly thinking about him and eventually falling in love. For instance, at a mixer, she unexpectedly enjoyed herself but wished Kusuo had been there to make it even more fun and imagined what he would do if he were present.

On August 6th, her birthday, she walks around aimlessly. Several men approach her, and she nicely rejects their flirting advances. She notices Kusuo across the street, recognizing him from her class. Admitting she nearly forgot about him because of his quietness in school, she incorrectly remembers his first name, believing it is Kunio. Considering his dull summer vacation, she approaches and talks to him. She greets him, but he politely bows and continues walking. Surprised by his brief reaction, she tries again, believing he thinks she is an illusion. However, Kusuo suddenly disappears in front of her, causing Kokomi to think that he was the illusion after all and begins liking him.
Since that day, Kokomi has always found it wrong that Kusuo treats her differently and has sworn to make him say “offu.”
