Think of this alternate reality as the lovechild born from the tropes for both magic and professional heroism. To give you a better idea of what I'm trying to go for, I'll be drawing inspiration from various manga, but core concepts will potentially come from My Hero Academia, Rave: Groove Adventures, Onepunch Man, and HunterxHunter. Hopefully, you've got a better grasp on the foundations I'm trying to build off from. It's kinda necessary later on once we go into more detail with the world building for this story.
For now, let's just settle for the gist of things. The year is 2020 and the world has been co-existing with magic for over 300 years. The reason behind the relative peace that's currently being maintained around the world is primarily due to the strict magical energy regulation laws observed by most countries. In this world, people with superpowers (referred to as Peculiarities) are the norm, and being a professional hero is a dream commonly strove for by many; and if it wasn't that obvious yet, you will be playing the role of one of these individuals. Cool, right? Or at least kinda interesting, I suppose.
By now, you probably have a vague idea on what the setting for this story. Next, we can talking about magic a bit more. When I say magic, it's more of an ambient energy that exists throughout the world. How it translates into Peculiarities is less spell conjuring and sorcery, and more of biological mutations. Peculiarities are special, superhuman abilities an individual can possess and are generally unique to their user. Aside from the occasional alteration and mutation of peculiarities, they are inherited genetically and typically manifest in children by the age of four at the latest. There are several laws and procedures to ensure the conscientious use of peculiarities. During elementary school, children receive counseling, in order to learn how to use and moderate their powers responsibly.
Aside from Peculiarities, magical energy is also used to fuel and create various artifacts, be it a common household object like a self sustaining lightbulb or kitchen knife that never goes dull, to prehensile and indestructible cloth bandages or a sentient mallet. Yeah, things can get weird here.
Anyway, before I go any further, maybe I could get a show of hands on those who wanna join in?
