History VideoGame / KarinsSkinDivingDiary

Info on the game can be found on its website [[http://www.foxeye.squares.net/abyss/karinsdiary/index.htm here]]. The updated Japanese and English versions of the game can be purchased at Website/{{DLsite}}.

This game is a short SliceOfLife of sorts that focuses on Karin's love for sea life and completing tasks for people that she meets, such as gathering certain materials and solving puzzles. Completing tasks unlocks more swimsuits Karin can wear, and gain access to more areas that she can dive into. But by the end, you are simply free to keep collecting fish in exchange for money in order to unlock diary episodes that go more in-depth on Karin and her friends' lives on the Storia Islands through artwork and storytelling. While the game looks innocent enough [[JustForPun on the surface]], this is also the second "Fox Eye [[HotterAndSexier ABYSS]]" game after ''VideoGame/BlueGuardianMargaret'', which means that all of the female characters are allowed to [[AvertedTrope avert]] NippleAndDimed unlike all non-ABYSS Fox Eye games, alongside other risque moments featured in the game.

* ExcitedShowTitle: Karin does indeed enjoy logging her skin diving adventures into her diary.

* EyesAlwaysShut: [[{{Meganekko}} Rimimi]] never opens her eyes regardless of her mood.

* {{Meganekko}}: Fox Eye sees a rare example in Rimimi, the dorky-yet-kindhearted owner of the Cosmos Harbor's tailor shop.

* AccidentalPervert: After meeting up with Kai on dry land, Karin gets embarrassed at him because his small and tight {{Fundoshi}} [[FemaleGaze makes it very easy to see his penis hiding in it]]. When Karin tries to explain this to Kai, she gets too flustered and CannotSpitItOut to him. [[spoiler:Kai returns the favor in his third diary scene, where unexpectedly encountering Karin topless arouses him to such an extent that he might as well not be wearing his fundoshi at all (which is then answered with a WardrobeMalfunction, even).]]

Interestingly, this game was originally going to be released for smartphones, first, but Fox instead made it available for [=PCs=]. This is the main reason why the game has a more vertical window display while it's running, as well as mouse-only controls due to their seamless correlation to touchscreen controls. A true smartphone release may be coming down the line, however.

* {{Meganekko}}: Fox Eye sees a rare example in Rimimi, the dorky owner of the Cosmos Harbor's tailor shop.

* VideoGameCrueltyPotential: If Karin drowns, the game then adds a prompt to rescue her with the push of a button. The game also allows you to take however long as you want to do this...

** Kana gets this treatment beyond the game, itself, going from being one of the [=NPC=]s of this game to becoming the titular protagonist of ''In the Aquarium: Sinking With Kana''.

* {{Fanservice}}: This happens almost everywhere in the game. Karin can unlock different swimsuits after completing tasks for people, and some of them are more {{Stripperific}} than others. Unlocking access to the Sea Trench will even allow Karin to take a dive in the nude, and even before then, her last actual outfit is a {{Fundoshi}} that only leaves her topless (due to fundoshis typically being worn by men and lack a top). All of the other female characters also get their moments in several normal and secret diary episodes, and even ThatOneGuy Kai ends up having what is so far [[FemaleGaze the lewdest fanservice out of any of Fox Eye's male characters]] (including Yuu following his ArtEvolution appearances in the circle beyond ''VideoGame/AquaCube''[='=]s release).

* HotterAndSexier: Like the previous ABYSS title, ''VideoGame/BlueGuardianMargaret'', this game [[AvertedTrope averts]] NippleAndDimed for all of the female characters, though this game lacks the more HGame-esque material that ''Margaret'' has (such as that game's implied "death-by-rape" GameOver artwork). Even [[ThatOneGuy resident young male Kai]] gets a bit of this treatment through FemaleGaze, where he wears a {{Fundoshi}} that does little to nothing to hide his genitals underneath it.

* ThatOneGuy: Most of the cast is female, but besides Karin's grandfather Ziji, there's also the {{Fundoshi}} diver, Kai, who looks to be the closest Fox Eye has had to a young male swimmer since Yuu of ''VideoGame/AquaCube'', or the [[WhatCouldHaveBeen boy that was going to appear in]] ''VideoGame/SacrificeGirl''. This is also referenced in-universe, as the diving club Kai is in is explicitly stated to be an ''all-girls'' club.

* {{Meganekko}}: Fox Eye sees a rare example in Rimimi, the {{Adorkable}} owner of the Cosmos Harbor's tailor shop.

* HollywoodPudgy: In diary episodes focusing on Rimimi, she gets too embarrassed about wearing her bathing suit in public because she thinks she's fat. While Rimimi is a bit chubbier than the other girls in the game, [[LesYay Karin still considers her]] [[NerdsAreSexy quite cute and attractive]], and like with the rest of the females, there's a secret episode of her stripping naked for extra {{Fanservice}}.

** [[PlayingWithATrope Played with]] in regards to Karin. If she stays under for too long, she ''will'' pass out from lack of air; however, she'll never actually die. Once Cubot rescues her, she'll [[UnexplainedRecovery be perfectly fine and ready to dive once more]]. (She will still fail her mission, though.)

A KineticNovel spinoff title, ''In the Aquarium: Sinking With Kana'', was released in 2019. [[AscendedExtra It stars one of Karin's friends, Kana]].
