Idea №13 Every Isekai ever x Worm
Due to some circumstances, Bakuda is recruited into ABB later than in the canon story. After Lung is defeated by Taylor on her first night out she fails to immediately take control of ABB. Desperate and angry after her failure she decides to use two of her experimental bombs on Arcadia and Winslow school buildings. She kidnaps two random students, one from each school, and implants the bombs into them (not into their heads, just into their bodies) and sends them to school. The original plan was to make the buildings change places with each other to show how versatile her explosives can be and that she can get anyone and anywhere. The signal was supposed to make the bombs go off simultaneously, but something goes wrong because of Arcadias faraday cage and instead of switching places both buildings disappear from the face of Earth Bet.
In some other (fantasy) world both school buildings appear right next to each other in the middle of an ancient forest surrounded by a "circle" of mountains. The trees look similar to the giant trees from Attack on Titan (Shingeki no Kyojin), their leaves are of darker shades of green than that of most trees on earth, and same goes for the colours of the tall grass that covers almost everything inside this mysterious forest. The buildings appear in the middle of an open field inside the forest, the closest arch-tree is just about 150m away. After some confusion and panic among the students and staff of both schools they discover that most, if not all students and staff now got superpowers. Each and every one of them got a blessing from the gods of this world during their "transportation", though they don't know about the origin of their powers yet and not all of them immediately discover exactly what their powers can do. The one thing that all of them have in common is that all of their bodies got tougher and stronger, though everyone has different levels of toughness and strength (those that have other powers are less tough and strong, while others have incredible toughness and strength, but no other obvious powers). The only exceptions are Taylor, the Dallon sisters and the Wards. All of them got two blessings because of their shards, so now they have 3 interconnected powers each instead of just one that they had before. During the first hour after their arrival, all students and staff are gathered outside and the struggle for power begins. The main two parties that struggle for the leading position are the Wards (together with the Dallon sisters, no Shadow Stalker tho) and the staff of both schools (so basically teenagers vs adults). None of the Wards are wearing their costumes and they use only the cheap mass-produced masks (provided by PRT) that they got from their lockers to hide their identities. Young gang members keep quiet (for now) and don't interfere because the Wards are present and because most of them still hope to somehow get back home. Taylor stays quiet too, for obvious reasons. After some time the debates are over and both parties decide to unite and separate their responsibilities. The Wards will act as guards/police, in case if there is any danger, and will be doing power examinations and training of other students in their spare time. The staff will be dealing with organisation and management of both students and resources. Glory Girl flies up into the sky and tells about their surroundings (giant forest surrounded by mountains) to the Wards and staff (Sophia already joined up at this point). They decide to conceal this information for now, while Taylor uses her new, improved powers to eavesdrop on their conversation and discovers that Sophia is Shadow Stalker. This discovery, along with the decision of the "authorities" to conceal important information from everyone makes Taylor not only not trust them, but also hate and despise them. Everything goes wrong on the second day after their arrival. The monsters attack the school building (didn't think through what kind of monsters though). The Wards (now including Shadow Stalker) and Dallon sisters deal with the monsters relatively, but in panic and confusion during the battle some of the students run into the forest. Some of the students were injured during the attack, Amy and some other students with newly discovered healing powers heal them. Immediately after that it is decided that half of the wards and staff will form search and reconnaissance parties, while the other half will stay in place to defend their "base of operations". Each party is made up of one Ward and two teachers. Before they leave some of the students apply "buffs" on the parties.
Note: That's it for now, maybe I will update this idea later. Didn't focus much on the actions of every character, how the outside world beyond the mountains is, what else there is inside the forest and etc. (mostly because this is just an idea for the story and not the story itself). The basic idea is that everything will go to shit real soon, people will form their own factions and will struggle for power for some time inside this forest until they get out to the outside world. The gangs and Sophia (along with Emma, Madison and some others) will form their own factions that will clash with each other and the Wards-n-staff faction, while Taylor does her best to stay away from this bullshit.
