When I Said, “You Can Be a Hero” to a Child With No Talent, He Really Started to Become a Hero, so I Acted Like I Knew What I Was Doing, Like I Was a Wise Master

The protagonist has been reincarnated and has been a hero all along. At first, he was motivated and had a haughty personality, but gradually, his motivation waned. He could defeat the Demon Lord with a sense of playing a game, but various complaints and the loss of motivation have plagued him. He wants to retire as a hero, but he can’t easily give up due to the deterrent force. So, he came up with an idea to create a new hero to take his place.

He tells one lie: that he is gradually weakening due to the Demon Lord’s curse…

“What!?”

The disciple is shocked. The world changes with just one lie from him. It’s a story about an invincible protagonist who wants to retire and attempts to lie about weakening to stop being a hero.
