    open/close all folders 

    Saiki Family 

Kusuo Saiki

The Main Character. A 16 year old boy with extremely powerful psychic powers. He could use them to effortlessly have anything he wanted, but instead opts to settle down for a peaceful and quiet life.

Kuniharu Saiki

Kusuo's father, a salaryman. Immature and greedy, he has fewer scruples about how his son should use his powers.


Kurumi Saiki

Kusuo's mother, an archetypical homewife. She very nice and kind, if a bit naive, and raised her son to never use his powers to evil.

    Students and Staff of PK Academy 

Riki Nendou

A really idiotic delinquent that thinks he is best friends with Kusuo. He's actually a nice guy, but his stupidity and appearance cause his good deeds to backfire.

Shun Kaidou

AKA: Jet-Black Wing

Shun Kaidou is the Secret Identity of Jet-Black Wing. Using the power of Black Pete, an godlike force imprisioned in his right arm, he fights to protect the world from the Dark Reunion, a Secret Society that plans to steal Black Pete and use its power to weed out the unnecessary elements from humankind and create a new world.

Or not. Actually, Shun Kaidou just believes he's Jet-Black Wing. He suffers from something called Chuunibyou ("Junior High 2nd Year Syndrome"), a delusion of grandeur that usually affects children that are going through the puberty, even though he's already 16 years old. He also thinks Kusuo is his sidekick.
  • Affectionate Parody: His appearance and the Jet-Black Wing's setup is a Cliché Storm from the Battle Shounen genre.
  • Calling Your Attacks: Even though he has no real attacks. He also uses this trope for mundane things.
  • Cloudcuckoolander: Although how much he really believes in his own fantasies is debatable.
  • The Cuckoolander Was Right: He's right about Kusuo having powers, but not in the way he thinks.
  • Coat Cape: Uses the jacket of his school uniform like this.
  • Conspiracy Theorist: Claims that Dark Reunion is behind every bad thing that happens.
  • Cowardly Lion: Has the guts to protect his classmates from a runaway snake despite being utterly mortified while doing so. Even Saiki is impressed by this act of bravery.
  • Friend to All Children: He's so friendly around children that he'll temporarily snap out of his Jet-Black Wing persona while talking to them.
  • Good Eyes, Evil Eyes: Usually, his eyes are narrow and simplistic. Whenever he lets the Jet-Black Wing persona slip, they turn very wide and friendly.
  • Jerkass Fašade: He acts arrogantly and pretentiously, but beneath his Jet-Black Wing persona, he's a nice guy.
  • Handwraps of Awesome: Supposedly, it seals Black Pete's power.
  • I Just Want to Be Special: Chuunibyou is caused by this.
  • Inferiority Superiority Complex: He's rather timid, but it's hard for anyone to tell when he's acting like the arrogant Jet-Black Wing all the time.
  • Large Ham: He talks like a Battle Shonen protagonist.
  • Miles Gloriosus: None of his exploits as the "Jet-Black Wing" never actually happened. At least he's capable of being brave when he's in a pinch.
  • Mr. Imagination: Has a severe case of Chuunibyou. He's convinced that in a previous life, he was a high level soldier of Dark Reunion who went rogue after he discovered their plans for world domination.
  • Peek-a-Bangs: Usually, only one of his eyes can be seen at a time.
  • Shonen Hair: It's very spikey, and likely intentional on Kaidou's part.
  • Super Drowning Skills: He can't swim, and he won't get into the water without wearing an unnecessary number of life preservers. It's revealed that he can swim fairly well if it isn't pointed out that he's swimming.
  • Terrible Artist: Tries to scribble down a picture of a child's lost dog based on its description. It ends up looking horrendous.
  • Vitriolic Best Buds: With Riki Nendou, after competing with him over Saiki's companionship.

Kokomi Teruhashi

The prettiest and most popular girl in the school. Everyone falls under her charms, except Kusuo.
  • Bitch in Sheep's Clothing: Kokomi acts nicely and kindly, but she's manipulative and hides a deep contempt for her classmates. Kusuo can see through the facade, in more ways than one.
  • Fille Fatale: She's great at attracting guys and making them do what she pleases.
  • Hello, Nurse!: Possibly the World's Most Beautiful Woman. In her presence, guys can't help but to stutter at her looks.
  • Joshikousei: Her school uniform is the traditional Japanese sailor fuku.
  • Informed Attractiveness: In her introductory chapter and onward, she doesn't stop reminding the viewer of how beautiful she thinks she is.
  • Slave to PR: Instead of acting like an Alpha Bitch, she tries to maintain the image of being nice and kind.
  • Spoiled Brat: Her true self. She can't stand the fact that unlike other guys, Saiki isn't hopelessly interested in her.
  • Spoiled Sweet: Her facade.

Chiyo Yumehara

A hopeless romantic girl with an unrequieted crush on Kusuo.
  • Affectionate Parody: To lovesick, romance manga protagonists.
  • Crush Filter: Whenever she imagines Saiki, he appears as a very idealistic, Bishounen love interest instead of the cynical, uninterested character that he is.
  • Joshikousei: Her school uniform is the traditional Japanese sailor fuku.
  • Hopeless Suitor: To Kusuo, who isn't interested in her. All of her attempts to get close to him fail because he predicts every single move she makes.
  • Thinks Like a Romance Novel: In her introductory chapter, she constantly comes up with scenarios that put her and Saiki into over-romanticized situations. Saiki, who can see these thoughts perfectly, is not amused in the slightest.

Kineshi Hairo

The over-enthusiastic Class Representative. His enthusiasm infects everyone, except Kusuo.
  • Affectionate Parody: Of hot-blooded, sports manga protagonists.
  • Class Representative: He's the class representative of Saiki's homeroom. As with everything he does, he's very proactive with his position.
  • Fist Pump: Does this when he's coming up with a plan, fired up to do something, or after he's accomplished something. He's just that enthusiastic about everything.
  • Hot-Blooded: An exaggerated version of this Trope.
  • Large Ham: He will even sweat dramatically without apparent cause.
  • Lovable Jock: Very athletic, and the most popular guy in the class, if not in the whole grade.
  • Manly Tears: Whenever he feels moved. Sometimes also inspires others to shed them.
  • No Indoor Voice: Most of whatever comes out of his mouth is delivered in a loud, over-dramatic voice.
  • Nice Guy: His hot-blooded passion for just about anything may come off as intense or annoying to some people, but he has a genuine desire to make others rise to their full potential.
  • Punny Name: "Hairo Kineshi" is a play on the word "Pyrokinesis".
  • Running Gag: His pants fall down whenever he trips.
  • Serious Business: Sports, teamwork, hard work, carrying heavy objects down a hallway...
  • Shonen Hair: His hair is red and spiked up.
  • Testosterone Poisoning: His fiery obsession with hard work, determination, and pushing himself (and others) to ridiculous limits is so outlandish that it crosses into comedic territory.

Reita Toritsuka

A high-schooler who was born the ability to see and talk to ghosts. He is aware that Saiki has psychic powers because a ghost told him so.
  • Covert Pervert: Lampshaded by Saiki, who's surprised that such an innocent looking person can be so indecent.
  • Guardian Entity: Has the ability to see each person's guardian entity thanks to his powers. His own personal guardian spirit is Nenou's lazy, deceased father.
  • I See Dead People: His special ability, which he's had ever since he was born.
  • New Transfer Student: Transfers to Saiki's school the day after he introduces himself to him. Saiki complains that the development is way too cliched.
  • Not So Different: When his psychometry forces him to see what Toritsuka has to see every day, Saiki sympathizes with his situation.
  • Screw the Rules, I Have Supernatural Powers!: He tries to obtain psychic powers so that he can peep at girls to his heart's content.
