** Natsuki is the only member of the titular club who keeps her head throughout the entire game, even as [[spoiler:the game starts to show its true psychological horror colors]]. Every character, including the PlayerCharacter, eventually shows various degrees of mental health problems, seeming shifts from their original personality, and/or lack of proper reaction to the things going wrong around them. Natsuki is the only one who's still herself at the height of the weirdness, and she's also the only one to try to ''do'' something about the problems by pleading with the player character to intervene.

** Natsuki is the only member of the titular club who keeps her head throughout the entire game, even as [[spoiler:the game starts to show its true psychological horror colors]]. She even writes a letter begging the player to help [[ShrinkingViolet Yuri]] with her SelfHarm problem and is the only member of the group who [[spoiler:doesn't commit suicide when she dies]].
** {{Subverted}} with Monika: In the first act, when everyone else's problems are still relatively normal (so Natsuki, for example, is suffering from lack of respect, poor self-esteem, and [[{{Tsundere}} anger management issues]]), it seems Monika is the only one who's totally fine and stable. [[spoiler:It turns out she's worse than any of the others and the cause of all the insanity going on since the end of the first act.]]

* Unlike [[WickedCultured Rire]] and [[SerialKiller Strade]], [[MadDoctor Sano]] in ''VisualNovel/BoyfriendToDeath'' isn't as gung-ho to kickstart the ColdBloodedTorture, and is considerably kinder ''if'' he warms up to you. It says something about how utterly ''fucked up in the head'' the "boyfriends" are when the MadDoctor is the closest to a sane man.

Picture this: Alice is the StupidEvil PsychoForHire, Bob is a {{Cloudcuckoolander}}, Henry is an EmptyShell, Charlotte is a ChaoticStupid [[ThePrankster prankster]], Karl is an ExtremeDoormat who's StupidGood, Daniel is Charlotte's AnnoyingYoungerSibling, Emily is a [[JerkWithAHeartOfJerk shallow]] {{sociopath}}, Maria often RhymesOnADime, Franklin is a MadScientist, Guy is a LawfulStupid {{Fundamentalist}}, Jacob thinks [[WindmillCrusader he's a hero on a grand quest]], and Lily is a MadArtist who's obsessed with her [[{{WaxMuseumMorgue}} wax "statues."]] Looks like your standard DysfunctionJunction. But then you have Isaac. Isaac is actually a very well-adjusted individual. He reacts with appropriate horror to things like Alice's finger and eyeball collection, Gardenia's tendency to attack anyone not believing in her religion, Franklin's experiments to revive the dead with science, and the crimes against nature that Franklin calls pets. Or reacts with either annoyance or bewilderment to things like Bob's [[InsaneTrollLogic warped logic]], Karl's HonorBeforeReason mindset (honor being always thought first in his case), Maria's insistence to rhyme all the time, and Jacob's [[HeroicWannabe delusions of being a hero]]. Isaac is the Only Sane Man and The Only Voice Of Reason in the room.

* Guy of ''WebOriginal/LifeInAGame'', being the only "real" person in his video game world, is the only one who questions the insane video game logic that everyone else seems to take for granted. It comes and goes, but the best example of it is in [[http://www.lifeinagame.com/pages/episode62.html Episode 6-2.]]

* [[GayOption Jaehee Kang]] in ''VisualNovel/MysticMessenger'' is by far the most reasonable member of the RFA, the charity organization you join at the start of the game. This trait is made apparent in the choices necessary to enter her route: she likes a main character who is optimistic and hard-working, but sensible and cautious. She claims that nothing special has ever happened to her (downplaying the fact that she's lost both of her parents so young) and is the only one in RFA who is rightly wary of you the beginning of the main routes, which makes sense because you're a total stranger entering a locked, private server, and suddenly living in their dead friend's apartment under extremely suspicious and mysterious circumstances. Whereas everyone else warms to you pretty quickly, you have to put in a little work to get her to begin trusting you.

Usually, but not always, a CastFullOfCrazy contains an Only Sane Man. Usually, he's prone to SanitySlippage. Sometimes, he's OnlySaneByComparison, and in more "normal" casts he'd be considered the craziest of them all.

* In ''Animation/ElArca'', everyone seems to be totally in love with the female panther Panty, all of them singing and dancing to her song "I will Survive", none of them seeming to notice she's talking about [[CarnivoreConfusion MURDERING AND EATING THEM]] except for the pig, who is clearly uneasy and suspicious, while everyone else, including the other prey animals, is completely oblivious to the actual words of the song, only really seeming to pay attention to Panty's... um... [[IncrediblyLamePun ''assets'']]

* Wrestling/TheShield: Originally, Wrestling/RomanReigns used to be this for the stable. [[Wrestling/JonMoxley Dean Ambrose]] was liable to fly off the handle at any time and Wrestling/SethRollins showed a startling amount of self-preservation during matches along with a sadistic streak after he ended the Shield to join Wrestling/TheAuthority. However, as the years went on, the actual OnlySaneMan turned out to be ''Ambrose'', at least in part because he was the only member to make peace with the end of the stable. Both Reigns and Rollins, meanwhile, underwent such severe SanitySlippage that they made even Ambrose at his worst look sane in comparison.
