Manga
- In chapter 182, we learn that the incident that permanently scarred Balam's face happened when he was only a very small child. A giant bird monster snatched the young Balam up and carried him off to his nest, where he had to hide behind a rock an entire night with no food or water. When Balam got hungry enough and finally dared to venture out and try to eat the bird's eggs, the mother bird was... unhappy, to say the least. We don't see the attack itself, but the next time we see young Balam after the incident, the entire lower half of his face is wrapped up in bandages. It's only thanks to his parents arriving in the nick of time to rescue him that nothing worse happened.
- The Heartbreaker Arc has several examples:
- In chapters 252-253, Jazz lets himself be tortured to buy time for the first-years he's paired up for the Heartbreaker. Jazz's strategy was to deceive the teachers into thinking that the first years are locked in a safe (actually fake), thus forcing any teachers he faced to get the safe's passcode from him in order to open it. Meanwhile, the students Jazz was paired up with would secretly escape to Allocer's side for protection. Unfortunately for Jazz, this results in him facing Marbas, who specializes in torture arts. The already-precarious situation gets so bad that Jazz is threatened with Marbas' stinger centipede if he doesn't give up the passcode.
- For the uninitiated: The stinger centipede penetrates the victim's wing root, damaging the spine and tearing the victim's nerves in the process, which would've been excruciatingly painful and potentially lethal (though Marbas does mention that they have medics on standby, as the staff wouldn't actually lethally harm the students). Fortunately, Iruma and his team busts in and saves Jazz just before Marbas can use the centipede on Jazz, but it's still horrifying.
- Chapters 256-257 has Atori blowing his cover when he gets too carried away beating up Sabnock and almost killing him during the Heartbreaker. This situation forces Sabnock to defend himself by unleashing his Wicked Phase, using special pills Balam prepared for him in case of a life or death scenario. Despite this, Atori still overpowers him and tries force-feeding him more pills to make his Wicked Phase go even longer, which is extremely dangerous. Thankfully, the situation becomes much less frightening once Balam arrives in the nick of time to stop Atori before he can go through with it.

Episode 18
- Amy Kirio himself. In his initial appearance, he seems to be a weak-but-friendly student who befriends Iruma and the others. However, this episode reveals him to be a sociopathic masochist who takes immense pleasure in the despair of others, including himself. His plan is to trap the entire student body during the Battora event and kill them all with a magic bomb, causing the Netherworld's denizens to revert back to their primal nature from their despair over the losses.
- The main reason Kirio's like this is because he was sent to a rehabilitation facility when he was born with little magic - when he accidentally causes his only friend's earring to fall into the water, he gets a nosebleed from watching her suffering.
- Worse, this reveal happens when Iruma ends up encountering him... all alone, in a hidden room, without Asmodeus or Clara to back him up. Amy even talks about trapping Iruma in barriers to helplessly watch the disaster unfold, and deliberately explains his origins to try and demoralize him into despair.
Season 3-Episode 12
- Iruma suffers a hallucination of his horrible parents wanting to take him back, which freaks him out even worse than many of the demons he's encountered.
