The Shonen anime is aimed at men under the age of 15. At this age, it is quite common for men to like stories that are bigger than real life, including interesting characters and, more importantly, an interesting world. This is because such stories create the perfect opportunity for escaping reality and fulfilling dreams. This is a fundamental reason behind the sustained success of the Shonen genre.
1 My Hero Academia

Trailer MY HERO ACADEMIA
Due to evolution, about 80% of the world's population has developed special abilities known as "quirks". Quirks are part of the user's body and give them superhuman abilities. This development led to a rise in dangerous crime and, as a way of dealing with this, the government made being a 'hero' a real profession.
A hero can be considered any licensee who uses their quirk to protect citizens from danger. This leads to an outburst of heroism, as many people who want to help others quickly jump at the opportunity to do so. Of course, some heroes only engage in these activities for money and some for fame. The idea of living in a superhero world, where you can make a living by saving people, is really fascinating.

An inventor is a scientist who understands the structure of matter and uses this understanding to decay objects or decay and then reconstruct that matter into something else. A fundamental principle of alchemy is the principle of equivalence exchange. This means that to create something, it takes or destroys something of equal value. This power system is one of the more detailed in the anime and, with its limitations, makes the use of alchemy more appealing.
In this world, the users of alchemy were people with special powers, able to perform magic and create magical items. The countries of this world all have their own principles and rules, and discovering and understanding these countries is an important part of the story.
