I was called incompetent, but in fact I was the strongest sage in the world ~ After being expelled from the magic school, I will become unrivaled with my hidden power ~

I, Taro Yamada (32 years old), died from overwork as a corporate drone and was reincarnated into another world.

However, I was reincarnated as a boy named Rein, who possessed only the lowest-ranked "Incompetence" skill.

Treated as a failure at the Royal Magic Academy, he was eventually expelled from the elite class.

But in reality, my "Incompetence" skill was just for show.

In truth, along with memories from my previous life, I secretly possessed world-class power!

In the lowest-ranked class, to which I was relegated, I gradually begin to unleash my true power, which I had kept hidden until now.

Together with my companions, also deemed failures, we will overturn the academy's norms in this exhilarating rags-to-riches fantasy!
