These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fan Translation: "Shibito" literally means "dead ones" or "dead people." Creative fan translations sometimes call them "deadites," after the Evil Dead franchise. "Yamibito" (yami meaning "dark") is sometimes creatively called "Darklings."
Narm Charm: The British voices from the first game can be this for some.
Nightmare Retardant: If you're unfamiliar with Japan's gun lawsnote Civilians do not have access to handguns or rifles, only shotguns with stiff restrictions; realistic-looking airsoft guns, as a result, are popular, Yoriko Anno asking "is that a real gun?" in response to Professor Takeuchi pulling a revolver from his bag can serve as this.
Rescued from the Scrappy Heap: Yoriko Anno spends most of the early game whining about how miserable she is and bugging Professor Takeuchi or whomever else she gets partnered with. After she gets shot, however, and gets a blood transfusion from Kyoya Suda, she apparently gets a dose of his nascent Bad Ass-itude.
Reiko escorting Harumi through the school in the first game. Mainly thanks to a game 'feature' where collected items aren't kept if you die and continue. Here, it's required that you use Harumi to grab an item just before the halfway checkpoint in order to proceed with the game, and so any deaths in the level will require you to start from the very beginning, lest you miss the item. Did I mention Harumi literally can't get anywhere NEAR a Shibito without dying, or that her AI routine for this level (seek a hiding place whenever you get caught) sometimes causes her to run BETWEEN you and an attacking enemy?
Bella having to sneak through a house occupied by a family of Shibito in Blood Curse, mostly for the same reasons. Being a 10-year-old girl, you will basically lose instantly if you even alert a Shibito and are not close to a hiding spot. This game for the most part fixed the issue where items aren't kept if you die and continue... but if you die at any point in this stage after collecting one archive item required to get another one a few stages later, you lose it and can't go back to get it without restarting the entire stage. Worse, about 50% of the time a pathing issue causes two of the three patrolling Shibito to get stuck on each other in the first-floor hallway, forcing you to alert one of them and run like hell to get them free. The stage is actually relatively quick and easy unless you decide to get the archive items all in one go, at which point it turns into a slog.
