YMMV / Karin's Skin Diving Diary!

• Goddamned Bats: As explained on the main page, dolphins and squids. Dolphins make all of the fish you attempt to catch swim away, while squids attract more dolphins. Catching either creature is a point percentage reduction to your score. You can also scare them away with Fuel Stones, but this can also scare away any valuable fish nearby that you were trying to catch. Using a Pearl, however, mitigates this by temporarily making dolphins and squids give you points, instead... at the cost of making other fish decrease your score.
• Hollywood Pudgy: 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, Karin still considers her quite cute and attractive, and like with the rest of the females, there's a secret episode of her stripping naked for extra Fanservice.
• Most Wonderful Sound: Simply put, anytime Karin surfaces from a dive to gasp for air, but especially if she just barely managed to avoid drowning while the player has a high score and bonus rate, ensuring them with a huge money reward.
• Narm: Unlike other Fox Eye games that cover a wide range of expressions and emotions for their characters during dialogue, this game only has a single "happy" portrait for each character that is used in all of their conversations, making it look rather awkward when they're being shocked, confused, or nervous at the moment. This isn't an issue during actual gameplay or the diary scenes, however, where every character shows more expressions, such as the frequent blue-faced panic Karin gets underwater when she's on the verge of drowning.
• Platonic Writing, Romantic Reading:
  • Fox claims that Karin and Kai are just good friends, but there are certain interactions between them that has fans wanting the two to go beyond that:
  • Within the game itself, there appears to be some Unresolved Sexual Tension where Karin constantly can't help but notice how easy it is to see Kai's penis under his Fundoshi. After Kai gives Karin her own fundoshi, she decides to take a dive while wearing it, even though it doesn't come with a top. She finds Kai taking an underwater nap, with her topless presence waking Kai up and making him very flustered and nervous at the sight of Karin's naked breasts. He tries to look away, but not only does he have a Luminescent Blush, he also has an erection that's almost entirely shaped by his fundoshi that quickly leads him to have a Wardrobe Malfunction.
  • Fox's first art of 2019 has Karin suffer a Wardrobe Malfunction of her own, where she loses her bikini bottom, not quite realizing that it ended up on Kai's head. The followup manga page also has both of them drown together when Kai accidentally bumps his head into Karin's back underwater.
