For a series that deals with severe psychological trauma, in a world where they manifest in physical ways (for better or worse), The Caligula Effect 2 is just as full of horrifying and unnerving moments as its predecessor.
- In a case of Ascended Fridge Horror, the game makes it clear that those trapped in both Mobius and Redo will not have an easy time even once they make it back to the real world. As they are trapped in this virtual world, their real world bodies starts to suffer from muscle atrophy which of course gets worse the longer that they are trapped with death being the eventual end point. This is what happened to Kobato which caused him to spend so much time in rehabilitation that his life was effectively ruined.
- Niko's reveal of her trauma: she's actually impersonating her dead twin sister, the real Niko. Her real name is Iori, The Unfavorite of her family. She longed for her parents' attention and despised her sister for hogging all of it, so when the real Niko died, Iori hoped that she would finally get the attention that she longed for. She got it, but in the worst way possible: her parents had a psychotic break and believed that Iori had died, and Niko was still alive. Up till this point, Niko has been relentlessly cheerful and enthusiastic, especially noticeable in WIRE with her manic, smiley-overdosed texts. Little by little over the course of her Character Episodes, however, the facade breaks, she has bursts of frightening anger, her voice noticeably deepens, and most prominently, the light in her eyes completely goes out. After she finally confesses to the protagonist, alone in the χ-Express, Iori threatens them and χ not to say anything or she'll kill them herself.
- The creepiness extends outside this. Every new WIRE topic from Niko past this point will suddenly lose the manic energy and the smileys, being simple, blunt, and acerbic messages as she drops the Niko act completely.
- Choosing to Kill Marie in Ch. 6. The lead-up to this was uneasy enough, with her Singularity Point powers completely infecting and warping the hospital into a nightmarish facility filled with phantoms, but the actual scene is horrifying much deeper, more psychological, more traumatizing ways. All this time, the Catharsis Effect has been shown to be explicitly non-lethal, turning victims back to normal with warped memories and negative feelings purged. Now, the protagonist kills Marie by stabbing her in the chest, complete with blood pooling beneath her hospital bed, and the horrified, shocked, clearly regretful reactions of the rest of the Go-Home Club. Then, Wicked reawakens and things get crazier and more unnerving from there...
