[[caption-width-right:350:Does [[OnlySaneMan Common Sense]] also count as a {{psychic power|s}}?]]
Kusuo Saiki is an OrdinaryHighSchoolStudent... Or at least [[IJustWantToBeNormal he tries to be one.]]

He's actually a boy with PsychicPowers. An [[TheOmnipotent incredibly powerful boy]] with [[NewPowersAsThePlotDemands every imaginable psychic ability]]. If he wanted to do so, [[PersonOfMassDestruction he could wipe out humanity]] [[TheEndOfTheWorldAsWeKnowIt in only three days]].

It sounds like [[GodModeSue he is perfect and has everything]], right? [[BlessedWithSuck Wrong!]]. He can't [[PowerIncontinence shut off his powers]], therefore his life is void of [[SpiderSense surprises]], [[NoChallengeEqualsNoSatisfaction challenges]] or [[ComicallyInvincibleHero sense of accomplishment]]. He also needs to avoid [[FriendlessBackground social]] [[CelibateHero interaction]], both because he wants to keep his powers secret and because he thinks of himself [[EvolutionaryLevels 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 ''Magazine/ShonenJump'', authored by Asou Shuuichi. It follows Kusuo's attempts in [[SliceOfLife living quietly]], [[CoverBlowingSuperpower hiding his powers]] and [[ObfuscatingStupidity avoiding standing out]]. Something that would be easier if not for his [[AmazinglyEmbarrassingParents quirky parents]] and a number of [[WackyHomeroom quirky classmates]] who insist to be friends with [[OnlySaneMan him]]. Cue lots of [[FirstPersonSmartass inner]] [[DeadpanSnarker snarkery]].

The [[Characters/ChounouryokushaSaikiKusuoNoSainan character page]] is in the development stages.
!!This series features examples of:
* AmazinglyEmbarrassingParents: Kusuo's parents, who act [[SickeninglySweethearts lovey-dovey]] all the time as if they were still teenagers... for his own misfortune.
* BeachEpisode: In Chapter 12, Saiki reluctantly visits the beach with Nendou and Kaidou after being threateningly persuaded by his mom to do so.
* ClapYourHandsIfYouBelieve: A bunch of unnatural phenomenon[[note]]basic shonen tropes such as YouGottaHaveBlueHair, MusclesAreMeaningless, and MagicPants[[/note]] 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 [[YouGottaHaveBlueHair 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.
* CrashIntoHello: PlayedWith. 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.
* CringeComedy: 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 ''Manga/AssassinationClassroom'') and Saiki visit Iruma and compete over the last piece of "Irumanjuu", a local delicacy. [[spoiler: 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 ''Manga/ShokugekiNoSoma'') at the Yukihara restaurant for a bite to eat. Unfortunately, Saiki's psychic powers grant him the ability to view every mental "foodgasm"[[note]]a person's erotic reaction to the food's taste[[/note]] at the restaurant. He promptly loses his appetite after seeing [[FanDisservice what his father's looks like]].
* {{Cloudcuckooland}}: Interestingly both played straight and {{Subverted}}. [[spoiler: Saiki used his power to make people believe unnatural things were natural, essentially creating all the weirdness so his own bizzare appearance blends in.]]
* DeconstructiveParody: Each psychic ability is discussed, relentlessly torn apart, then taken to its logical and hilarious conclusion.
* EvolutionaryLevels: Kusuo thinks he's different enough to be considered a different species, the next step in the human evolution. [[spoiler:He also thinks Nendou is below the modern man and above the neolithic one]].
* FirstPersonSmartass: Much of the humor of the series comes of Kusuo mentally [[DeadpanSnarker snarking]] at [[OnlySaneMan everyone else's crazyness]].
* FourthWallObserver: 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 [[SelfDeprecation about his manga]] and ''Shonen Jump''.
* JawDrop: Nendou's reasoning about Takahashi's illness cause this.
* HighSchool: PK Academy is a small private highschool which most of the characters attend.
* InfectiousEnthusiasm: Hairo causes this kind of situation and Kusuo plays the grumpy guy. Kusuo doesn't become really infected, but ends being dragged along anyway.
* InnocentInnuendo: Nendou creates this kind of situation sometimes, verging into the AmbiguouslyBi territory.
* LeaningOnTheFourthWall: The physical education teacher has the students play dodgeball because [[Manga/KurokoNoBasuke basketball]], [[Manga/{{Kurogane2011}} kendo]] and [[Manga/{{Haikyuu}} volleyball]] are already being played.
* LoadsAndLoadsOfCharacters: The manga is steadily moving in that direction.
* LuckyCharmsTitle: This is one of the few manga, if not the only one, with a Greek letter in its title.
* OnlySaneMan: Kusuo, who is by far the ''less'' normal guy in Earth.
* MagicPants: Kusuo uses his powers to [[InvokedTrope invoke]] this in-universe. Because it's much better for this trope to happen then to have the [[RealityEnsues fabric between the legs tear during an action sequence]], right?
* MediumAwareness: Kusuo can read the captions with expositive text.
* AMindIsATerribleThingToRead: 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. [[PlayedForLaughs It's rather hilarious]].
* MyFriendsAndZoidberg: Takahashi gets this treatment in Kusuo's narratives.
* NebulousEvilOrganisation: 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 [[{{Chuunibyou}} Kaidou thinks]].
* NewPowersAsThePlotDemands: PlayedForLaughs and {{Deconstruction}} purposes instead DeusExMachina.
* PunBasedTitle: "Sainan" ("Disaster") [[LuckyCharmsTitle is written as "]]Ψ [[LuckyCharmsTitle Nan"]] ("Psi Nan"). Some chapter titles get the same treatment.
* PunnyName: The word "saikikku" means "psychic". The main character is named '''Saiki Ku'''suo. Other characters names are puns about specific psychic powers.
* PsychicPowers: Kusuo, [[ExactlyWhatItSaysOnTheTin 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 [[spoiler: see ghosts]].
* ShoutOut: Many, usually to other manga of Jump.
** Chapter 5: Nendou prefers that the protagonists of ''Manga/{{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 [[Manga/KurokoNoBasuke basketball]], [[{{Manga/Kurogane2011}} kendo]] and [[Manga/{{Haikyuu}} 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 [[Manga/OnePiece 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 ''Manga/{{Naruto}}'' that reveals [[TheReveal 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 ''Manga/AssassinationClassroom''.
** Chapter 27: Saiki shudders at the thought of having to share his 48 cups of coffee jello with every member of Music/AKB48.
* SickeninglySweethearts: Kusuo's parents. That is, of course, if they aren't fighting with each other.
* SliceOfLife: A story about the everyday happenings and grievances of an insanely powerful psychic teenager.
* StrangeMindsThinkAlike:
** Nendou and Matsuzaki-sensei have similar ideas about [[spoiler:first aid]].
** In the {{Crossover}}, both Kusuo and [[Manga/AssassinationClassroom Koro-Sensei]] [[spoiler:regularly travel to the city of Iruma to eat irumanjuu at the Sakurayama Observatory]].
* TakeThat: At the time that ''Manga/{{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, [[SuspiciouslySpecificDenial but clarifies he's not talking about ''Shonen Jump''. Twice]].
* TalkingIsAFreeAction: One of the perfectly normal things that happen in this world, [[InvokedTrope thanks to]] Saiki's powers.
* TrademarkFavoriteFood: Kusuo loves his [[SweetTooth coffe jello]], and Nendou is always inviting his pals to eat ramen.
* YouGottaHaveBlueHair: Some characters have unrealistic hair colors, including Saiki, who was born with pink hair. [[PlayingWithATrope It turns out that]] he brainwashed the entire world into thinking that "[[InvokedTrope pink is not an unnatural hair color]]" in an attempt to [[ExploitedTrope 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.
