''Suika'' is a visual novel by Circus, split into intertwined stories over a two week time period in a small village.

The first chapter stars Akira Kazuma and his return to the town where he briefly went to school. He meets a miko who turns out to be one of the two friends he made when he was living there. There are constant flashbacks detailing the time the two went to school together along with Itsuki's sister Sayo and the growing love triangle between them.

The second chapter is about Souji Kamishiro and the relationship between him and the local father and daughter artists Ritsu and Sayaka Shirakawa. Ritsu's art is rather disturbing and so is his normal manner. It also has an alternate route involving side character Mie Wakabayashi after the True Ending of the VN is achieved.

The third chapter is about the love triangle between Touko and the Misaka siblings, Akane and Yoshikazu. Touko is intensely devoted to Yoshikazu, but also extremely jealous of any of his relations with absolutely anyone else. Especially his non blood related little sister Akane, towards whom he has a secret attraction which isn't helped along by her rather suggestive behavior.

The fourth and final chapter is the one that finally returns to the first protagonist Hiroshi Inaba. The story also addresses the little silver haired girl with red eyes, black clothes and a small black cat doll. Who is she, and why does she keep acting so strangely when people notice her? And if she wasn't trouble enough, Hiroshi's father is dying and his sister has a [[IllGirl potentially fatal heart condition]] and is scheduled for a surgery soon.

Adapted into a {{Hentai}} and released in the U.S. as ''Wet Summer Days'', which focuses on the first, second, and fourth episodes of the game. The visual novel has been officially released in English by Mangagamer. There's also a sequel, ''Suika Niritsu'', that centers on a new set of characters, but it hasn't been licensed yet.

[[VideoGame/{{Touhou}} No relation to a certain oni]]. Nor a watermelon. Compare ''VisualNovel/EfAFairyTaleOfTheTwo'', a game also released in English by Mangagamer with a similar setup and the same artist.

'''This story provides examples of:'''
* AbusiveParents: Itsuki's parents probably deserve some kind of award.
* AngstySurvivingTwin: Itsuki. [[spoiler:But not really. See DeadAllAlong. The "dead" twin may count, as she was actually in a [[ConvenientComa coma]], not dead.]]
* AngstWhatAngst: {{In-Universe}}. Sayaka, probably best illustrated in the scene where she makes friends with Mie, who is horrified at how the town treats her despite how kind she is.
* BleachedUnderpants: All of the all-ages releases, the most recent of which was ''Suika [=A.S+=] Eternal Name'', released during the summer of 2007 and consequently the last new release, not counting Mangagamer's English localization of the original [=A.S+=] UpdatedRerelease in 2009, for the series.
* BrokenAce: Souji is good at essentially everything and a complete chick magnet (random people coming up to him and trying to kiss him isn't something entirely unexpected for him) but has a personality which is about half facade.
* BrotherSisterIncest: Touko's biggest worry in the third chapter because they're NotBloodRelated, so it's okay!
* ChickMagnet: Souji.
* ChildhoodFriendRomance: One of the happier chapters focuses on Sayaka, the childhood friend of Souji. She actually has two endings, though for the second ending she basically shares a love triangle route with Mie that focuses more on her.
* ClingyJealousGirl: Touko.
* ConvenientComa: [[spoiler:Sayo]] get out from hers just at the end of the chapter.
* DeadAllAlong: [[spoiler:Itsuki.]]
* DownerEnding: [[spoiler:First chapter and arguably the third as well.]]
* DrivenToSuicide: [[spoiler:Akira confronts Minase-san at the end of the first chapter with this result.]]
* DysfunctionJunction: Most of the cast has some severe issues, though there are a few examples. Chapter one is probably the worst about it.
* FailureKnight: Archimedes. Yes, the cat.
* FeminineWomenCanCook: Sayaka gets irritated because Souji is a much better cook than she is.
* FootnoteFever: Names of Japanese holidays, foods, religious ideas, etc. are often left untranslated in the Mangagamer translation, with a note to look up what it means in the included .pdf translation notes file.
* TheGadfly: Akira was quite the joker in high school, which was apparently what attracted Sayo to him. [[spoiler:This attitude is beaten out of him by the end of his chapter.]]
* KnifeNut: Souji always carries a silver knife in his pocket.
* LiteralSplitPersonality: [[spoiler:Chinatsu and Ojou.]]
* LittleSisterHeroine: Akane really plays it up. [[spoiler:A horrible subversion.]]
* LoveMakesYouEvil: [[spoiler: Both heroines in the third chapter... poor Yoshikazu...]]
* LoveTriangle: Several, but most prominent in the first and third chapters.
* LoveYouAndEverybody: In Sayaka's alternate route, she asks Souji if he likes Mie. Of course he does! It's not until noticing her irritation at his misunderstanding that he realizes she meant romantically. If you're playing the Mie version of this route, he can't come up with a proper answer.
* MatchmakerCrush: Akane.
* {{Miko}}: Itsuki, the daughter of the priest.
* MindControlEyes
* MisunderstoodLonerWithAHeartOfGold: [[spoiler:Ritsu.]]
* MurderTheHypotenuse: [[spoiler:The climax of Itsuki's route involves pushing her sister down the stairs that were always thought of as dangerous on the spur of the moment and assuming she's killed her. The result is actually the other way around; Sayo lived through the fall and entered a coma, and Itsuki's head was bashed in with a shovel when her father returned.]]
* MultipleEndings
* MysticalWhiteHair: Ojou the shinigami. The hair color is noticed in story but mostly shrugged off with the assumption she's a foreigner.
* NiceHat: Ojou refuses to remove it
* NoExportForYou: Averted with Mangagamer's official localization of the [=A.S+=] UpdatedRerelease in 2009; though it does apply for ''Niritsu''.
* NoNameGiven: [[ExactlyWhatItSaysOnTheTin The nameless girls.]]
* NonHumanSidekick: Archimedes.
* NotBloodRelated: Akane and Yoshikazu. [[spoiler:Does not play out how you'd expect.]]
* PolarOppositeTwins: Itsuki and Sayo.
* ThePollyanna: Sayaka is very well adjusted considering the entire town seems to hate her and her father
* ThePowerOfLove: [[spoiler:The only thing that will save a shinigami.]]
* RedEyesTakeWarning: Averted. Ojou is probably the sweetest and most innocent character in the story
* SetRightWhatOnceWentWrong: [[spoiler:A red herring in the third chapter.]]
* {{Shinigami}}: Ojou
* SiblingTriangle: A rather unpleasant variant that ends with [[spoiler:Itsuki pushing Sayo down the stairs and thinking she's killed her, followed by her father beating her head in with a shovel.]]
* SiblingYinYang: Sayo and Itsuki both fell in love with Akira.
* StepfordSmiler: Souji and Mie.
* TitleDrop: In the true ending.
* TokenMiniMoe: Ojou.
* TomatoInTheMirror: [[spoiler:Itsuki upon realizing that she shouldn't be a miko. Oh, and also that she's dead and buried in the backyard rather than her sister.]]
* TomboyAndGirlyGirl: Sayo and Itsuki.
* TwistEnding: [[spoiler:Akane's reaction to choosing her over Touko, when up to this point she had been far more sympathetic and likable than Touko.]]
* YamatoNadeshiko: When we first see Touko, she does her best to embody the ideal. [[spoiler:However, the later routes show her to be an obsessed yandere.]]
* {{Yandere}}[=/=]CuteAndPsycho: [[spoiler:Akane does not react well if you choose her over Touko, which will be rather surprising considering the preceding story.]]
** [[spoiler: Touko too...she isn't violent about it, but in her ending it's revealed pretty much the whole chapter's events were orchestrated or manipulated by her to drive ''everybody else'' out of Yoshikazu's life but her. Even his therapist. ''Damn''.]]
