The third BoysLoveGame by [[NitroplusCHIRAL Nitro+CHIRAL]] of VisualNovel/TogainuNoChi fame, Sweet Pool begins with the return of Sakiyama Youji to his Catholic High School after a long absence due to illness. Suddenly he finds his life changing in unbelieveable ways as his fate becomes entangled with his [[TheStoic stoic]] classmate Shironuma Tetsuo, [[{{CloudcuckooLander}} eccentric]] upper-classman Okinaga Zenya and [[{{Keet}} friend]] Mita Makoto.

Sounds like your typical school boys love setting right? Except that this being a [[{{Nitroplus}} Nitro+]] production means that the story is also infused with horror of the most potent kind. Filled to the brim with PrimalFear and BodyHorror, all heighted with a [[CrowningMusicOfAwesome brilliantly creepy soundtrack]], this is definitely not a game for the faint-hearted.

The manga adaptation has been licensed in English by [=SuBLime=].

----
!!This game provides examples of:

* ADateWithRosiePalms: Youji, several times. [[BodyHorror It makes bad things happen]]
* AsTheGoodBookSays: The game starts with God's command for humans to multiply from the Old Testament
* [[spoiler: BabiesEverAfter]]: Youji and Tetsuo's [[MultipleEndings true ending]]. Part BittersweetEnding, part FridgeHorror considering the premise.
* BigEater: Makoto
* BlondGuysAreEvil: Played straight with Zenya, possibly subverted with Tetsuo
* BodyHorror: Constantly, to the point that this is more of a horror game than a romance game.
* {{Cloudcuckoolander}}: Zenya
* [[spoiler: DeathBySex/ DeathByChildbirth]]: A literal example in Youji's and Tetsuo's true end.
* EyeScream: There's a reason why Zenya's right eye is always covered by an eyepatch.
* {{Expy}}: Makoto looks an awful lot like [[VideoGame/{{Persona 4}} Yosuke Hanamura]] with longer hair.
* FaceOfAThug: Kitani.
* FateWorseThanDeath: In Zenya's ending [[spoiler: Youji gets captured and raped by Zenya. Timeskip a few weeks or months and Youji is still imprisoned in a dark room, treated as a sex pet, vomiting up almost everything he eats and wondering when he will die. Oh, and when he's finally too [[DeadlyEuphemism tired]]? Zenya plans to [[MummiesAtTheDinnerTable stuff him]] so that he'll stay by his side forever.]] [[{{Nitroplus}} Nitro+]] doesn't do half-assed bad ends.
* ForgetsToEat: Youji, though it's almost an active choice.
* GenUrobuchi: Only in a consultant role, [[VisualNovel/SayaNoUta though the influence is clear...]]
* {{Gorn}}
* [[spoiler: HomosexualReproduction: The parasites only choose human males for reproduction, as women's womb is an obstacle for them since intestines are their habitat. The baby is [[BodyHorror "born"]] from [[MisterSeahorse both partners]]. [[MindScrew Don't ask]].]]
* IfItsYouItsOkay: Youji feels this way towards [[spoiler: Tetsuo]]
* [[IllGirl Ill boy]]: Youji, to the point that he had to stay behind a year.

* {{Keet}}: Makoto is usually cheerful and friendly. ''[[BewareOfTheNiceOnes Usually]]''.
* {{Love Makes You Crazy}}: [[spoiler: Or pheromones in Makoto's case.]]
* LudicrousGibs: Any animal that eats [[spoiler: the "seed meat" born from the parasites]] explodes into this.
* MindFuck: Oh ''so'' much.
* MisterSeahorse: One of the first sign that Youji isn't completely normal is when [[spoiler: he keeps giving birth to small living lumps of flesh.]]
* MoodWhiplash: Not in the game but after finishing any one of the [[TearJerker depressing]] and usually downright scary endings the website containing the Dev team's production notes is unlocked and amongst them, horrors of horrors, is [[spoiler: a chibi picture of all the characters relaxing around a kotatsu, including Onnushi-sama [[note]]basically a giant slab of living meat covered in pulsating veins[[/note]] in a Santa suit.]]. Finishing all the endings will grant you a CG of [[spoiler: the cast engaging in a pillow fight]].
* MultipleEndings: Notable for there being [[spoiler: no happy ones]]
* OnlySaneMan: Kitani in the Okinaga household.
* OverdrawnAtTheBloodBank: Youji literally oozes blood whenever [[spoiler: Tetsuo is concerned]].
* [[AliensMadeThemDoIt Parasites made them do it]]: Kinda justified since the parasites are [[spoiler: the damned souls from places like Sodom and Gomorrah]].
* ParentalAbandonment: Youji's parents were killed in a car accident when he was young.
* PlayingThePlayer: See SadisticChoice below.
* PromotionToParent: Youji's sister
* PrimalFear: Of the bloody, squicky kind
* RapeAsDrama
* SadisticChoice: [[spoiler: Since this game has no happy endings ''every single choice'' you make basically just decides how Youji will meet his end]].
* ScareChord: Occasionally.
* ScaryShinyGlasses: Kamiya gets a few of these moments.

* SmellsSexy: Played completely straight since Youji, Tetsuo and Zenya all release pheromones.

* StalkerWithATestTube: [[spoiler: Kamiya and co.]] ships [=Tetsuo/Youji,=] for nefarious purposes.

* [[TakeCareOfTheKids Take Care Of My Innards]]: [[spoiler: Zenya asks this of Kitani.]]
* {{Utsuge}}: The game is infamous for its dark-as-hell and sometimes downright depressing atmosphere, resulting in it being a major TearJerker for some players.
* VisualNovel
* WombLevel: The whole game is basically one since the interface has conspicuous amount of pulsating veins, along with distinctly organic sounding sfx.
* {{Yakuza}}: Zenya's dad was a former Yakuza boss and his underling Kitani was one as well.
* {{Yandere}}: Makoto becomes one out a jealousy. [[spoiler: He goes as far as threatening Youji with a knife, and in one ending rapes and cannibalizes him.]]
* YankTheDogsChain: Every time Youji and Tetsuo's relationship [[CharacterDevelopment takes a step]] [[HopeSpot forward]], expect the plot to come in and kick everyone in the stomach.
* YoungerThanTheyLook: Tetsuo is a year younger than Youji but manages to hide his age and work part-time as a bartender. In addition, due to the art style, [[ArtisticAge everyone looks like they are in the 20s]].
