A few generations ago, children were born who showed strange characteristics which became known as quirks. As time went by, quirks spread throughout the human population, until at the time MHA begins 80% of the world's human population, and even some animals, possess some kind of quirk. In this developing world of super-powered folks, some people use their quirks to commit crimes, which means that there are also superheroes who use their quirks to fight these criminals.
Izuku “Deku” Midoriya is a boy who grew up idolizing these superheroes, especially the most powerful one of all, All Might. But Deku was one of the unusual people who was born without any quirk, which meant that his hopes of becoming a superhero himself were essentially nil. But an encounter with All Might opens up a way for him to acquire a powerful quirk and continue to pursue his dream at the the hero training high school, UA.
Much of this first season is about Deku getting into the school, participating in various class activities, and meeting other students. But towards the end, he and his classmates get into real battles with villains who invade the school grounds.
It might be interesting to compare MHA to something like X-Men, because they are opposites of each other in a lot of ways. In X-Men, mutants are the abnormal ones, the ones who are seen as been different and dangerous. In the MHA world, quirkless humans have become abnormal, and growing up Deku suffers from being one of those few people around who have no quirk. A boy he grows up with, Katsuki “Kacchan” Bakugou, looks down on and bullies the quirkless Deku when his own explosive quirk begins to show and develop.
This not-quite-friendship, not-quite-rivalry between Deku and Baku is one of the main elements and sources of tension in the story.
Deku is an intriguing character to have as a main lead for this story. Even before he was given his quirk, he is shown as being intelligent and analytical, as well as courageous. In many ways, his quirk is more of a problem for him up to this point then a help, as whenever he uses it his body is still unable to handle the power it unleashes in him.
Not all content is what would be called “family-friendly”. Some of the humor is suggestive and crude, and a few of the outfits are revealing.
With the anime appearing to be very popular and season 2 already being announced, one good thing to know is that the manga is very far ahead of the where the anime is now. Hopefully viewers of the anime will not need to deal with fillers for some time. While the tone of this first season has been mostly lite, if it continues to closely follow the manga then that will change. With almost 100 chapters already finished in the manga, there have been at least two story arcs that have been very intense.
I enjoyed this first season of the anime, and recommend it.
