It could be Deku. Since he is the main character in the original series, it would be interesting to see how he adapts to the new management system. Maybe he could be at the forefront of advocating for changes that benefit all students.
I think Todoroki could also be a great main character for this fanfiction. With his complex backstory and powerful quirk, he could play a significant role in the new management. For instance, he might use his position to address the issues related to the training and mental health of students under the new system.
Another option could be Bakugo. His brash and competitive nature could lead to some interesting storylines within the context of the new management. He might initially resist the changes but then gradually come to realize the benefits and end up leading in his own unique way.
One possible interesting plot could be a new management system in the hero school that focuses on a more collaborative approach between students and teachers. For example, students could be involved in creating new training programs based on their own unique quirks.
There's no way to know for sure without reading the fanfiction. However, it could potentially be a side character that the author has decided to make the focus. For example, a character who has always been in the background but suddenly their disappearing act becomes the central mystery. It could also be a hero who has been mentioned briefly in the original series but is now given a whole new story arc in this fanfiction where their disappearance is the key plot point.
One idea could be that the characters find a new home as a secret hideout from villains. They might use their quirks to build and customize it, making it a safe place full of unique features.
In My Hero Academia, the management style involves a lot of training and assessment. Heroes have to go through rigorous education and tests to improve and prove their abilities. Also, there's a system of supervision and guidance to ensure they act responsibly.
Maybe the new home is a large treehouse - like structure built in a forest. It would blend in with the natural surroundings and provide a peaceful yet secure place for the heroes. They could have different levels for different functions, like a training area on the lower levels and sleeping quarters on the upper levels. It could also be a place where they can study and analyze the quirks of villains and come up with counter - strategies.
It could be a new student at U.A. High School. Maybe someone who was a hardcore gamer in their previous life and now has to adapt their gaming skills to the hero world. They would have unique ways of approaching hero training and battles.
Bakugo could also make an interesting main character. His explosive personality combined with a gamer ability would be really cool. He could be super competitive in the 'gamer' aspects of the story, like ranking up in a hero - ranking system that works like a game. And he would be all about proving he's the best, not just in real - life heroics but also in the game - like challenges.
It could be a new student at U.A. High School. A cyborg with a unique quirk related to their mechanical parts, like the ability to fly using jet - propelled limbs. This character could be the main focus as they learn to control their powers and make friends among their classmates.
All Might could also be an interesting choice. If someone was reincarnated as a younger All Might, they could change some of the events that led to his decline in health. They could also learn from his mistakes and become an even more powerful and long - lasting symbol of peace.
It could be Deku. Since he is the main protagonist in the original My Hero Academia series, it would make sense for him to be the main character in this fanfiction as well. He could be the one who discovers the 'Flames of Hope' power and has to learn how to control it while still using his One For All ability.
