With an easy to understand premise of "boy with psychic powers wants to impress girl he likes by joining the bodybuilding club", it's so much more than that.
However, the real goal of the series is not that.
It's something mentioned very early on by Mob's mentor, Reigen, which is just
"Be the best person you can be".
Mob Psycho 100 is not about this awkward kid dealing with espers and ghosts and all things supernatural, while trying to live his school life.
It's about that awkward kid growing up as a person through all the different people he meets, and at multiple times it's referenced how Mob is just a "blank slate" and he needs to "be somebody". It's here where you see the biggest difference between Mob and anyone else with psychic powers in the show who constantly think they're better than everyone else, while Mob is trying to BE like everyone else.
It's the one story-based manga I can say has the perfect ending.
Not because everything went his way, but because everything that happened is consistent with the message of the show.
Definitely check this out if you want a heartfelt manga, and if you don't like the art at first, give it some time and it'll definitely grow on you.
