-> ''"Do friends cover each other with blood from bloody noses?"''
-->- '''Serika'''

Nao is just a normal high school kid who's a tad shy and withheld. He doesn't have any friends but seems just fine with it. Enter Serika, a girl in his school looking for a friend. Also, she is the single strangest person he has ever met, constantly having nosebleeds whenever she looks at him and rarely showing an expression on her face besides absolutely serious. She's also decided that he's going to be her new best friend...

''Choku!'' is the first manga by Nico Tanigawa and holds many similarities to their more popular series of ''Manga/NoMatterHowILookAtItItsYouGuysFaultImNotPopular'' However, instead of making comedy off of the social ineptitude of the main character, it instead forces said character to grow by introducing someone even more socially inept than him to an absurd degree.

----
!! This manga provides examples of:

* {{Adorkable}}: Nao.
* AllWomenAreDomsAllMenAreSubs: Pretty much every girl in Nao's life has power over him. {{Justified|Trope}}, as he's rather weak willed and physically average.
* AlmostKiss: {{Played for Laughs}} and instigated by Serika's mom.
* AndNowYouMustMarryMe: Serika constantly invokes this on Nao, usually around other people.
* BadassAdorable: {{Inverted}}. Nao is not {{badass}} by any means...but his cuteness is described by Serika as a "Dangerous Weapon." Whenever she looks at him, she forgets everything going on around her. See {{Class Trip}} to see why this is a dangerous thing.
* {{Bishonen}}: Nao, according to Serika.
* [[spoiler:BlackComedyRape]]/[[spoiler:AttemptedRape]]: [[spoiler:Serika ends up in a fit of lust at one point and forces her self on Nao after thinking that he wanted them to have their first time. Nao fails to fight back, but his cute expression causes Serika to have a nosebleed so bad that she passes out from it before anything could happen and thinks the whole experience was a dream.]]
* BrainlessBeauty: Serika once says she thinks Nao having low grades is a charm point. He doesn't exactly agree.
* ButtMonkey: Nao, usually entirely by accident on Serika's part.
* CanNotSpitItOut: Nao [[spoiler:after Serika thinks the two are dating.]] [[spoiler:So Serika's mom does it for him. By accident.]]
* ChivalrousPervert: Serika. She would do anything for Nao, but she also loses a lot of blood by just looking at him.
* ClassTrip: Nao misses out on his, due to Serika looking at him sleeping in her sidecar, causing her to take her eyes off the road at the worst possible time.
* ClosetOtaku: Nao, but a minor one.
* {{Cloudcuckoolander}}: Serika, to an absurd degree.
* CoolSidecar: {{Inverted}}. Serika's sidecar is certainly interesting, but an adorable looking seal isn't exactly cool.
* {{Cosplay}}: Nao is forced to dress as a Vocaloid for a part time job. A female one. Serika dresses as Black Rock Shooter.
* CovertPervert: Nao. He's not that big of a pervert, but he certainly doesn't look like one at first glance.
* DatingSim: Nao's favorite type of game. To his displeasure, Serika forced him to play some with her.
* DirtyMindReading: Serika believes she can read someone's mind by looking in their eyes. She picks up dirty thoughts from Nao, who instantly denies all of them.
* EmotionlessGirl: {{Inverted}} with Serika. She feels plenty and expresses herself, but it's usually with the same deadly serious expression.
* {{Fanservice}}: From time to time, usually with Nao, amusingly enough. Then there's the chapter at the arcade.
* HGame: Nao plays these...once with Serika.
* HypocriticalHumor: Serika criticizes a comedy act for using crude humor in chapter 20.
* JapaneseDelinquents: [[spoiler:Serika pretends to be one after she finds out Nao wasn't dating her.]]

* [[SirSwearsalot Miss Swears-A-Lot]]: Serika is found of using the S word as it was intended to be used.
* {{Nosebleed}}: From the female lead, for a change.
* NoSocialSkills: Both the main characters, but mainly Serika.
* OldFashionedRowboatDate: [[spoiler:Nao, while trying to make up with Serika.]]
* ParentalAbandonment: Nao's mom leaves on a business trip a few chapters in.
* [[spoiler:RelationshipUpgrade]]: As of Chapter 17.
* RomanticComedy
* RunningGag: Nao crossdressing, nosebleeds from Serika, Serika appearing at the worst time, and many others.
* SickEpisode: Nao has the cold and Serika skips school to nurse him back to health. A mix of {{Crowning Moment of Funny}} and {{Crowning Moment of Heartwarming}}.
* ShorterMeansSmarter: {{Subverted}}. Turns out that Serika is a genius. She's 10 cm taller than Nao.
* {{Shotacon}}: Nao's teacher. She might also be a {{Lolicon}}.
* SliceOfLife
* StalkingIsLove: Overtime. {{Justified|Trope}} as Nao never really had someone care as much about him as Serika and she's overall very nice...just strange.
* StupidSexyFlanders: Nao has this affect on most everyone when crossdressing.
* TinyGuyHugeGirl
* ToiletHumor: In the very first chapter, Serika meets Nao and says that she finds taking a shit with her lover (who she already sees Nao as) is romantic. She is aware she is in the boy's room. She prefers it there.
* UnsettlingGenderReveal: Let's just say one of the arcade employees had an interesting run in with Nao in the bathroom...
* UrbanLegends: Nao and Serika start one when a janitor thinks the two are a ghost. With all the blood Serika left behind, this isn't surprising...
* WeaknessTurnsHerOn: Serika really likes Nao in part of his very un-manly body and personality.
* WholesomeCrossdresser: In the first chapter, Serika forces Nao to wear a wedding dress. He wears it well. He pretends to be a female student later to try and help another girl scared of men, which comes back to bite him...
