Hanten Yuusha no Gyakuten Eiyuutan ~[munou wa i ran] to tsuihou sa retanode munou dake de party kunde maou o toubatsu shimasu ~

“Let’s banish the incompetents!”

The main character, Rikuto, supports his friends from the shadows and is a key figure in leading them to an S-rank party. However, he is the only one in the world with zero magic power and his status is mediocre, so he is branded as “incompetent” and expelled from the hero party.

Then, why is he the key figure? It is because he has a unique skill called ≪Inversion≫.

This ability reverses the status of the enemy, making it possible to turn a high-level monster into the same status as a low-level monster such as a goblin or slime. For this reason, the party to which Rikuto belonged was able to defeat any strong enemy they encountered with ease.

The rest of the party members, who did not know this and mistakenly thought they were strong, came to regret it. And later, after their downfall, they resented Rikuto and vowed to banish him from the world.

This is the story of an exiled boy who joins a party with others who were also called incompetent and were ostracized, defeats the Demon King, and reverses their reputation.
