Plot Summary

The CHAPTER AU is separated into arcs, just like BnHA. The overall plot is that Denki creates a group chat with UA, and eventually more characters join, and it turns more into a story than a group chat.

Pregame Arc
No real plot happens here. This arc is just a bunch of crack, exposition, and character establishment. Kirishima is established as a trans cannibal. Dabi is afraid of a cow. Crying in parking lots is normalized. Wearing socks isn't gay. Kirishima kidnaps Shoji at some point, and turns Denki into a cannibal by getting him hooked on human meatballs.Momo adopts most of the characters, and Shigaraki is called Thicc. Shinsou and Denki are bashed for being horny, and this will become one of the key moods of their relationship. The League of Villains and the UA heroes stop fighting each other. Toga gets a cat named Squishy, who tries to eat Tokoyami. Izuku is turned into a spider due to their excessive Monster drinking. Shigaraki eats chapstick Mei designs. At some point, Hawks has to go to the doctor for the concussion he received while flying into a window, much to Dabi's chagrin. Setsuna and Izuku become a couple. Kirishima kidnaps and attempts to eat Aizawa. Endeavor joins and subsequently gets bullied, kidnapped, tortured, and attacked by black widows, the last of which is courtesy of Izuku. Eri joins, and Denki teaches her educational versions of inappropriate songs. Everyone gets along.

Body Swap Arc
Due to a mishap with an invention of Mei's, most of the UA students and staff end up switching bodies with each other. It is during this time that All Might and Endeavor are revealed to be in a sexual relationship. Having been in the hospital, Shoji actually switches bodies with a doctor named Jared, who loves his wife and swears he isn't gay. Jared gets bullied by the cast and is more or less a gag character. Eventually, order is restored, and everyone is relieved to be back in their own bodies. Except Jared, whose life sucks.

Angst Arc
! TRIGGER WARNING: This arc contains attempted suicide and self-harm.

Overhaul kidnaps Eri, Tokoyami, and Denki. He poisons Tokoyami and end up using Denki to kill Eri with the help of his allies, Eren and Sekkai. Shortly after the rescue, Kirishima becomes the king of the sewer clowns. Then it is discovered that Eren and Sekkai put a plate in Denki's head to control him. Denki attempts to kill both Bakugou and Shinsou, but is saved by Shinsou's dirty talk. Shinsou gets exorcised, and there is a brief exchange with demons. Kirishima decides he wants to become a demon, and has Eri do a ritual to turn him into one. However, the ritual gives everyone a scare when Kirishima appears to be dead. Eri runs off, thinking it's her fault, and Denki snaps at Shinsou, causing him to run off. Kirishima is revived, and Denki realizes that Shinsou is mad at him, so he goes to the woods to kill himself. Shinsou also makes an attempt on his life, jumping from the roof of UA. As they are portaled to the hospital by Kurogiri, the poison in Tokoyami's system acts up. Nejire and Kendou separately blame themselves and internalize the self-hatred. Kendou is comforted and dissociates, but Nejire self-harms. Shinsou and Denki recover in the hospital and learn that Eri is still missing. Overhaul is the prime suspect, but it is revealed that Eri has a degeneration disease that he was trying to heal, and that all the negative actions are Eren's and Sekkai's, not his. Though everyone is skeptical at first, it turns out to be true. Overhaul joins the heroes in taking care of Eri. A shapeshifter named Evie disguises herself as Endeavor and kidnaps Shouto, only to "save" him for the public image. It is unknown at this point in the story why someone would help Endeavor's image like that, especially since Endeavor himself is seemingly unaware that it happened. Shortly after, Shouto and a recovered Tokoyami save a girl named Aria from bleeding out in an alley.

Foreshadowing Arc
Kirishima gets thousands of rubber ducks, and Katsuma befriends a bear named Coco. Several tea parties are had, and a night of drinking reveals that Denki is part cat. Mei's mother makes an appearance, and with the help of a form-changer named Ruuki, Denki and Shouto disguise themselves to fool her. In the process, Shouto commits a few murders, including that of Mei's mother. He is also revealed to be unable to feel pain, and to have a regeneration ability. Tokoyami is revealed to be involved with the yakuza. Yui admits her feelings to Shouto, and they begin a relationship. Shouto insults Uraraka, which Overhaul claims is the effect of a quirk. During his "recovery", he grows more attached to his father, to the point where he believes Enji did nothing wrong. Though it is too late, it is revealed that Enji has been injecting Shouto with something, "brainwashing" him. When he is confronted, Shouto throws a fit in Endeavor's favor, and Dabi brings him outside. However, it isn't really Dabi: it's Evie. She passes Shouto to Caro and Sakura, two new faces in the cast. As she goes to retrieve Enji, though, her identity is discovered, and she is forced to use a cyanide pill to avoid giving information. Kirishima eats her body. While plotting to get Shouto back, Eren claims he wants to switch sides and work with the heroes. He gives information on Caro and Sakura and says there will be an attack on the square.

Villain Todoroki Arc
Caro, Sakura, and an unknown villain called Frostburn wreak havoc on the square, causing a massacre. While most of the heroes try to save the civilians, a few like Yui and Shinsou fight back. Tokoyami notes that while Eren told them about Caro and Sakura, he never mentioned Frostburn, who is using fire. He confronts Eren, who responds that it's because Frostburn is the heroes' buddy, not his. It is revealed that Frostburn is Shouto, apparently having been further brainwashed. He appears to not remember who he is, and gets agitated atthe mentioning of his real name, insisting that he be called Frostburn instead. The villains escape, and several more attacks follow, a game of cat-and-mouse between the heroes and the villains (who call themselves the Strikers). Eren disables the plate in Denki's head. It is revealed that the Strikers work for someone known as "X". Overhaul is revealed to have been working with them, for Eri's safety, but he regrets that when Enji burns children at a park. He promises to be good. Saiko stabs Eren fatally when going for Overhaul, claiming she believed he would betray them again. With his dying breath, Eren names Aria as the key to recovering Shouto's memories. Tokoyami throws Eren's body out back. Another attack happens, after which Eren is revived by Siren. Shouto is captured, and his memories are about to be restored by Aria when Denki stops them, claiming to be controlled again despite Eren saying he disabled the plate. It is revealed that Denki is a traitor, and there never was a plate, and the heroes and Eren had been deceived. Denki claims he did it all for Shinsou, wanting to protect him. He takes the heroes to the Strikers hideout, where Kirishima is revealed to be X. On Kirishima's orders, Shouto burns Bakugou, turning his body to ash, and threatens Eri, saying she will die too if everyone doesn't bow. Everyone bows except Saiko, who is revealed to also be a traitor. Shouto burns Eri, killing her.

WW3 Arc
Denki has been imprisoned, as the heroes are unsure whether he can be trusted. However, he escapes, being freed by Frostburn in exchange for the codes to nuclear warheads Mei has developed. Overhaul has disappeared, and Shinsou grieves the loss of his sister until he hears her voice telling him to go to the park. On the way, La Brava uses her pro gamer hacking skills to reveal that Shinsou's Eri hallucination is actually Caro using technology to lure him to the park to be killed. La Brava manages to get through to Shinsou, who tortures Caro until Denki's throat is accidentally slit. Shinsou rushes Denki to Recovery Girl. Before he passes out, Denki reveals that Kirishima plans on bombing the United States. Meanwhile, Tokoyami and Dark Shadow have been separated by the Strikers. Tokoyami is freed, and Dark Shadow joins the Strikers in exchange for Tokoyami's guaranteed protection. However, when tasked to blow up a train, Dark Shadow realizes he like being on the dark side. Frostburn attempts to win over Yui, but Shouto takes control and Frostburn has to leave. Saiko works on making La Brava fall in love with Frostburn to get her on the Strikers side. The USA gets bombed. Bakugou and Eri come back, but something’s amiss. Bakugou says he's supposed to be Alpha Particle, working for the Strikers, but he wants to be a Hero spy instead. Eri tells the story of how a mouse saved her from an operating table. Dark Shadow rejects Tokoyami during an attack on the bank. A slime monster calling itself Beta asks Mei about her satellite. Zukan, Masu, and Ankha show up. Zukan and Eren fight, and then there's an attack during which Eren gets taken and Aizawa gets killed. Denki seems like a traitor again, and the Heroes meet Jaeg. Shinsou trades himself for Eren. The arc ends with the reveal that Eri is on Kirishima's side, and the world (except for the Strikers, Ankha, and Masu) is now Quirkless.

Quirkless Arc
Frostburn tells the Heroes all they have to do to regain their quirks is answer a riddle: ''When I sleep, I die. When I speak, I cry. When I jump, I eat. When I yawn, I retreat. Can you guess what I am?'' He says it could take literal seconds, or it could take ages to get the answer. Everyone dead is revived by Ankha. The answer is "No." The riddle says "Can you guess?" not "What am I?" which makes the answer No. Everyone is revealed to have been in a training simulation designed by Saiko. All the "villains" except Enji and Calibris were in on it, and this was Aizawa's way of introducing the new students Caro, Eren, Sekkai, Masu, Zukan, Ankha, and Sakura, as well as the new allies Jaeg and Aria.

Endpocalyse Arc
Enji is still high on his villain spree and decides to be a villain for real. Shouto has been acting weird, and when Tokoyami follows him he realizes that Shouto hasn't given up his Frostburn title yet. Katsuma is rescued from the villains, but not before his blood is taken. Frostburn threatens Tokoyami to keep his mouth shut. Denki adopts a cheetah named Spot, and Shinsou has a lion named Simba. Shinsou uses his quirk to get Endeavor to admit that he’s using Frostburn. Frostburn saves Eri and kills Akari, Endeavor’s partner, but gets injured in the process. He escapes the hospital, warning Shinsou to keep an eye on Denki. Milo, a shapeshifting lynx, gets taken by a Jaguar named Koro. Denki meets up with an online friend, Matthias, who drugs him and takes his blood. As he recovers in the hospital, Shouto reveals that he had lied to Matthias and told him Denki was Touya, because they are after Touya’s blood. Kurogiri evacuates the subway system, having been notified by Shouto that there is a bomb somewhere. After the subway is evacuated, it is revealed that Shouto lied. Dabi appears, but suspicions are raised about his true identity. Sure enough, Eren throws himself on "Dabi" as he explodes, having apparently been a suicide bomber disguised as Dabi. Denki, Shinsou, Kurogiri, and Tokoyami go to Overhaul's lab, suspecting him, but find him tied up. Overhaul says Zukan stole some of his lab stuff, and is working for the Capri Sun company. He brings out Moya and Sanda, two young girls created from Denki's and Shinsou's combined DNA.

Capri Sun Arc
Moya and Sanda make themselves known. Seshiru gets kidnapped in an alleyway on their way home from running errands. Zukan tries to talk Tokoyami into jumping off the roof of UA. Tokoyami doesn't want to, but he slips. Luckily, Sophia creates a cloud to save him. Tokoyami walks in on Moya and Zukan plotting, and records it. Denki is ordered by Moya to do something, but Denki reveals to Tokoyami that he can’t be controlled due to certain circumstances. It turns out Moya is only working with Zukan to try to keep Eri alive, as the villains have her hostage. During a UA attack, Zukan goes to kill Tokoyami but is stopped by Calibris, who injures Zukan. Endeavor takes Zukan away, and Calibris announces he missed Tokoyami and is sorry and wants to rejoin the heroes. Everyone breaks into the Capri Sun factory to save Eri, Milo, Koro, and Bakugou. Matthias is killed by Overhaul and Tamaki, and Zukan is brutally mauled to death by Calibris. Tokoyami also takes his liver back to UA for Mei. The Capri Suns are revealed to be poisoned, with a massive handout planned at the next day’s festival. Moya is revealed to have DNA structure similar to a Nomu’s, much to everyone’s confusion. The cats are given collars to translate their meows. At said festival, Shinsou and Moya get captured, the poisoned Capri Suns a hoax to get them. Shouto secretly tells the others how to get them back, and he gives Moya a key to the warehouse Dabi is captured in. Upon arriving and waking him up, he is revealed to have lost his memory due to the villains’ drugs. Shouto claims there is an antidote at the base, but it will be risky to get. Ruuki is called in to disguise Kurogiri as Caro and Calibris as Overhaul, and the two of them with Shouto's help get the antidote. They are seen by Endeavor along the way, and Shouto distracts him while Kurogiri and Calibris escape. The antidote works. Returning to UA, Overhaul attempts to give Moya more "medicine", but calls in a woman named Kaya who is revealed to be the real creator of Moya and Sanda. She did not know about Moya's condition, having only been paid to fix her. She and Overhaul leave, and Moya falls asleep with Tokoyami. Shouto comes back, and Yui and Tokoyami fight over whether or not tomatoes are good. The Dinosaurs In Love song gets some people emotional, and others annoyed. Caro comes to visit, and everyone barely stops Moya from doing something in the library. It is decided that everyone will stay to see what happens.

Terminal Arc (in progress)
Fumi stays with Moya, where some extra clues are gathered. Moya is given a different version of the medicine, but she eats too many. It’s revealed that the medication speeds up the Nomu process, and that Caro is one too. It’s also revealed to all but Eren that Caro is Eren’s supposedly dead sister. Calibris turns out to be the brains behind the operation, and during a fight Spot is killed, and Moya is kidnapped. Ankha brings Spot back, though. Moya is found in a warehouse, but refuses to go back because it will hurt if she does. Shinsou goes with her to the villains’ place, where Moya begins training. TO BE CONTINUED
