- Episode 0 has the sudden arrival of KADO witnessed by the protagonist in the airplane that was just about to go of. Things only get worse when KADO makes contact with the airplane in Episode 1. Poor Hanamori...
- Yaha-kui's unintentional Mind Rape of Shindou.
- The rather obvious reasons why the Wam is posing a very real danger to humanity.
- The fact that the UN was more concerned with the Wam, rather than the one who brought them in the first place.
- Yaha-kui zaShunina already used rather weird devices whose obvious potential to be abused with disastrous consequences have been regularly acknowledged, but the Sansa is in a tier of its own. While not necessarily as directly dangerous as the Wam, it is terrifying in every way that the Wam isn't. For starters, it looks like a human brain. When it activates, the Sansa essentially divides itself in ''loafs'' and starts assuming movements that make it look like either a bacteria/ameba and in doing so it gradually starts resembling a worm. Then, it causes those who view it (even on TELEVISION) to see multiple versions of themselves while their surrounding looks like a Disney Acid Sequence on crack. In Genno's case, one of his duplicates at first looks just as confused as Genno - almost like a mirror image - but then suddenly delivers a rather unnerving Psychotic Smirk.
- Things also get pretty disturbing when estimated billions of people have a reaction to watching the Sansa on television in Episode 8, which almost looks like a mass epilepsy attack!
- Yaha-kui zaShunina himself delivers a quite chilling borderline-Slasher Smile at the end of episode 8.
- The Nanomis-heim is an incredibly dangerous device which effectively enables almost anyone to become a Space Master and/or Time Master.
- Yaha-kui's Love Confession in episode 9. You wouldn't think it'd be that scary, right? Think again— he does this while time is slowed down in the KADO, and while he talks you see sped up versions of Shindou slowly losing his mind and his health over an almost 3 day period without food or contact with the outside world. By the end of it he's staring blankly at the sky, unable to move due to starvation, while Yaha-kui looks over him sweetly.
- While Yaha-kui knocks down all of the clone Shindos, upon closer inspection one can see that some of them were put down in very uncomfortable positions. Some have their legs backwards or bent at certain angles, and some are twisted entirely.
- Kanata having to watch a clone Shindo be demolished in the Kado, complete with bone crunching sounds. It's not the real thing, but she's still clearly disturbed by the sight.
