Mori, the Port Mafia's leader, is strong enough to curtail Raynare and get her to agree to work for him without even needing to attack her, just using his sheer killing intent to cow her. She even compares his level of bloodlust to Kokabiel!
After the U.A. Entrance Exam, while hanging out at Dagobah Beach, Izuku, Ibara, and Ochako come across Itsuka Kendo being threatened by a trio of drunk guys who are trying to force her to have sex with them, and that they'll make her if she turns them down, even mentioning that she'll get in trouble if she uses her Quirk to defend herself. Luckily, the devil trio shows up and manages to scare them off.
The USJ incident becomes worse for several reasons:
Rather than just bringing in several Mooks, Shigaraki went and brought Muscular.
The Nomu is Riser and Ravel's brother, meaning that the League is experimenting on Devils as well as humans. And the Phenex flame regeneration makes it powerful enough that, even though All Might still has One For All, he has even more trouble beating it, requiring a total of 500 blows to defeat it.
Bakugo stumbles onto Freed murdering a priest and gets shot repeatedly. If Azazel hadn't saved him, he definitely would have died.
Xenovia pisses off Akutagawa when she tries to attack him, only to fail to do any damage become he's using a Quirk, not a Sacred Gear or magic, and she would have been seriously injured or even killed by Rashomon if Izuku hadn't intervened, and he gets part of his wing torn off for his trouble. Fortunately, he can get that healed with Phenex tears, but he still has a huge scar left, and had he timed it just a little differently he would have lost an arm, and he can't regrow those.
Everything about Lailah. The fact that she's deliberately based on Airachnid from Transformers: Prime, complete with a similar history with Griselda that Airachnid has with Arcee, should tell you a lot about her, and none of it good.
She's first mentioned by All For One's doctor, confirming that she has ties to the League of Villains.
She first encounters the ORC when they're hunting a stray devil, only she got to it first. When they investigate the warehouse she's in, they find that it's full of human corpses, and she takes interest in killing Ochako to add her witch head to her "collection".
The worst part of it all? She's an angel, who has avoided Falling due to Loophole Abuse, having been created to be a Torture Technician for God during the Great War, and has been freelancing since the war ended.
As the Sports Festival ends, Stain is approached by Lailah, and then the League shows up, looking to recruit the former...
Mizu has been confirmed to be a Stain attack survivor, and Ingenium's attack has caused her horrible nightmares.
Xenovia trying to get Izuku to leave her pregnant, even though it is obvious he is uncomfortable with the idea at best, feels less like the harem hijinks it means to evoke and more like an outright rape attempt, particularly when Izuku attempts to leave only for her to grab him and pin him to the floor. And everything happens because Xenovia's lack of social skills kept her from realizing what she was really doing until the other girls in the Peerage give her a What the Hell, Hero?.
Overhaul gets so pissed about Eri escaping that he rips apart the grunt who was supposed to be watching her and puts him back together twelve times before finally letting him die.
It's made clear that Eri could have been in pain for the rest of her life, given how little care Overhaul took to put her back together if she had been in his "care" for too much longer.
A doctor warns Rosalba that overusing her Quirk on wounds like Ingenium's could cause cancerous growths to form.
Although it's only to make a point, Fukuzawa still puts a katana to Bakugo's throat faster than the latter can even react.
Not only is the original Nomu confirmed to be Ravel's brother, but the League is turning other supernatural beings into Nomu as well.
Itsuka stumbles across Lailah, and the sadistic angel takes a personal interest in her. And then the chapter ends...
Zero's Quirk lets him control the movements of those within twenty meters of him using their own bones. Even the narration lampshades how creepy his Quirk is, especially since he makes a Nomu contort in ways that are clearly unnatural even for its altered biology.
When Milia brings up Asmodeus, Itsuka has a reaction that heavily implies that she has Fake Memories and extreme fear of a mysterious face...
When Fat Gum arrives to help the police against a group of drug dealers, one of them takes Trigger in order to fight back, becoming powerful enough to hold his own against Fat Gum, Suneater, and all the officers at once.
Apparently the chaos of the early Quirk era was so bad that the Satans seriously considered revealing devils to the world to try and settle things.
Tartarus Prison apparently has lots of allegations of abuse and human rights violations.
A mysterious girl in a hoodie pays Giran to look for several unnamed villains. The frightening part is that the payment is heavily implied to consist of broken Evil Pieces. Not only that, but Giran knows what they are and their value on the black market, even broken.
Not only is the Old Satan faction now aware of Ingvild and Itsuka and seeking to kill them, but they have what appears to be Itsuka's mother, seemingly either brainwashed or reanimated, under their control. Even worse since it's all but said that the figure Itsuka remembered attacking her mother and trying to kill her was Creuserey Asmodeus, and he wants to finish the job now that he knows Itsuka is alive.
Of the people attacking for Gasper not only destroys the Switch Izuku gave him, turning it to marbles and popping one into his mouth, but he implies that he'll do the same to them if they resist.
Bobby Ball, the man with the marbles Quirk, manages to one-up himself by using it on the head of a Khaos Brigade magician who's wounded, despite them still being capable of helping him.
In addition to Dabi and Toga joining the League, there's a mysterious rogue exorcist girl, meaning they have additional firepower against the Devil heroes...
