Manga / Chounouryokusha Saiki Kusuo no Ψ Nan
Does Common Sense also count as a psychic power?
Kusuo Saiki is an Ordinary High-School Student... Or at least he tries to be one.

He's actually a boy with Psychic Powers. An incredibly powerful boy with every imaginable psychic ability. If he wanted to do so, he could wipe out humanity in only three days.

It sounds like he is perfect and has everything, right? Wrong!. He can't shut off his powers, therefore his life is void of surprises, challenges or sense of accomplishment. He also needs to avoid social interaction, both because he wants to keep his powers secret and because he thinks of himself as too different to relate to normal people.

Chounouryokusha Saiki Kusuo no Ψ Nan (The Disaster of Psychic Kusuo Saiki) is a gag manga published by Shonen Jump, authored by Asou Shuuichi. It follows Kusuo's attempts in living quietly, hiding his powers and avoiding standing out. Something that would be easier if not for his quirky parents and a number of quirky classmates who insist to be friends with him. Cue lots of inner snarkery.

The character page is in the development stages.

This series features examples of:

  • Amazingly Embarrassing Parents: Kusuo's parents, who act lovey-dovey all the time as if they were still teenagers... for his own misfortune.
  • Beach Episode: In Chapter 12, Saiki reluctantly visits the beach with Nendou and Kaidou after being threateningly persuaded by his mom to do so.
  • Clap Your Hands If You Believe: A bunch of unnatural phenomenonnote  suddenly became real because Saiki brainwashed people into thinking they were natural occurrences. Most were done for his personal convenience.
    • To prevent his pink hair from standing out in a country full of black haired individuals, Saiki brainwashed the entire world into believing that "pink hair is a natural hair color". Their belief in this statement resulted in the sudden existence of other unnatural hair colors.
    • Saiki did the same thing with several other tropes. For example, he made it so "injuries that heal immediately are not unnatural" after arousing suspicion when he healed a kid who badly scraped his knee.
  • Crash-Into Hello: Played With. Chiyo plans to set up a romantic meeting with Saiki by carrying a bunch of books and "coincidentally" bumping into him. Saiki, aware of her plan and not interested in her scheme, uses his psychic powers to dodge her attempt.
  • Cringe Comedy: It would have far less cringe if you couldn't see the story from Saiki's point of view. Having constant telepathy and X-ray vision sucks.
  • Crossover:
    • In a one-shot chapter, Koro-sensei (from Assassination Classroom) and Saiki visit Iruma and compete over the last piece of "Irumanjuu", a local delicacy. Saiki eventually splits it in half and shares it with Koro-sensei.
    • There is a two-page Jump special where Saiki and his dad visit Soma (from Shokugeki no Soma) at the Yukihara restaurant for a bite to eat. Unfortunately, Saiki's psychic powers grant him the ability to view every mental "foodgasm"note  at the restaurant. He promptly loses his appetite after seeing what his father's looks like.
  • Cloudcuckooland: Interestingly both played straight and Subverted. Saiki used his power to make people believe unnatural things were natural, essentially creating all the weirdness so his own bizzare appearance blends in.
  • Deconstructive Parody: Each psychic ability is discussed, relentlessly torn apart, then taken to its logical and hilarious conclusion.
  • Evolutionary Levels: Kusuo thinks he's different enough to be considered a different species, the next step in the human evolution. He also thinks Nendou is below the modern man and above the neolithic one.
  • First-Person Smartass: Much of the humor of the series comes of Kusuo mentally snarking at everyone else's crazyness.
  • Fourth-Wall Observer: Saiki's inner monologue is specifically addressed to the reader. He's aware of the existence of his manga (and the pilot one-shot, for what matter) and often makes snide remarks about his manga and Shonen Jump.
  • Jaw Drop: Nendou's reasoning about Takahashi's illness cause this.
  • High School: PK Academy is a small private highschool which most of the characters attend.
  • Infectious Enthusiasm: Hairo causes this kind of situation and Kusuo plays the grumpy guy. Kusuo doesn't become really infected, but ends being dragged along anyway.
  • Innocent Innuendo: Nendou creates this kind of situation sometimes, verging into the Ambiguously Bi territory.
  • Leaning on the Fourth Wall: The physical education teacher has the students play dodgeball because basketball, kendo and volleyball are already being played.
  • Loads and Loads of Characters: The manga is steadily moving in that direction.
  • Lucky Charms Title: This is one of the few manga, if not the only one, with a Greek letter in its title.
  • Only Sane Man: Kusuo, who is by far the less normal guy in Earth.
  • Magic Pants: Kusuo uses his powers to invoke this in-universe. Because it's much better for this trope to happen then to have the fabric between the legs tear during an action sequence, right?
  • Medium Awareness: Kusuo can read the captions with expositive text.
  • A Mind Is a Terrible Thing to Read: Since Saiki's power of telepathy cannot be shut off, he hears every thought within a 200 meter radius whether he wants to or not. Constantly listening to others' pointless, disgusting, or annoying thoughts, as well as being robbed of any sense of surprise or excitement, has turned him into a perpetual snarker. It's rather hilarious.
  • My Friends... and Zoidberg: Takahashi gets this treatment in Kusuo's narratives.
  • Nebulous Evil Organisation: Dark Reunion, the secret, ominous organization that wants to conquer humanity and steal the unfathomable power sealed within Kaidou's right arm. At least, that's what Kaidou thinks.
  • New Powers as the Plot Demands: Played for Laughs and Deconstruction purposes instead Deus ex Machina.
  • Pun-Based Title: "Sainan" ("Disaster") is written as "Ψ Nan" ("Psi Nan"). Some chapter titles get the same treatment.
  • Punny Name: The word "saikikku" means "psychic". The main character is named Saiki Kusuo. Other characters names are puns about specific psychic powers.
  • Psychic Powers: Kusuo, obviously, but it's implied that there are other PSI users in the world. In Chapter 17, he meets Toritsuka Reita, a young man who can see ghosts.
  • Shout-Out: Many, usually to other manga of Jump.
    • Chapter 5: Nendou prefers that the protagonists of Nisekoi and Pajama Na Kanojo end up with Onodera and Makura, respectively.
    • Chapter 6: The physical education teacher has the students play dodge ball because basketball, kendo and volleyball are already being played.
    • Chapter 12: Kaidou is unable to swim despite wearing a bunch of life preservers, to which Saiki retorts, "What are you, did you eat the Devil's Fruit?"
    • Chapter 17: When Saiki explains his psychometry powers, he sees a vision of a customer reading an issue of Shonen Jump. The issue contains the chapter of Naruto that reveals Tobi's true identity.
    • Chapter 23: The moon that young Saiki flies past has a huge chunk of it carved out, making it look like a permanent crescent. It looks exactly like the blown up moon from the first chapter of Assassination Classroom.
    • Chapter 27: Saiki shudders at the thought of having to share his 48 cups of coffee jello with every member of AKB48.
  • Sickeningly Sweethearts: Kusuo's parents. That is, of course, if they aren't fighting with each other.
  • Slice of Life: A story about the everyday happenings and grievances of an insanely powerful psychic teenager.
  • Strange Minds Think Alike:
    • Nendou and Matsuzaki-sensei have similar ideas about first aid.
    • In the Crossover, both Kusuo and Koro-Sensei regularly travel to the city of Iruma to eat irumanjuu at the Sakurayama Observatory.
  • Take That: At the time that Nisekoi, Pajama na Kanojo and Koisome Momiji were all being serialized, Kusuo monologues about as lately everything was about love and that romance wasn't an interesting matter, but clarifies he's not talking about ''Shonen Jump''. Twice.
  • Talking Is a Free Action: One of the perfectly normal things that happen in this world, thanks to Saiki's powers.
  • Trademark Favorite Food: Kusuo loves his coffe jello, and Nendou is always inviting his pals to eat ramen.
  • You Gotta Have Blue Hair: Some characters have unrealistic hair colors, including Saiki, who was born with pink hair. It turns out that he brainwashed the entire world into thinking that "pink is not an unnatural hair color" in an attempt to not stand out from his naturally black haired peers. The result? Every color of the rainbow is now considered a "natural" hair color in this world.
