I Reincarnated as the Knight Order’s “Failure Master”

All I’m doing is just game strategy guide…

I died from overwork and was reincarnated as “Kaien,” the hated mob instructor from an RPG I had played extensively. He’s the famous “Failure Master” known for crushing rookies without talent.

The first person I was assigned to handle was a girl named “Lina,” who in the original story was destined to have her heart broken and leave the order.

“I’ll change this girl’s bad ending future!”

I am not og author

With that determination, I made full use of my knowledge from the original work. I imposed training that seemed meaningless and harsh on the surface. But it was all a training method to exploit loopholes in the game’s mechanics and unlock hidden stats.

As a result, Lina, who had been a dropout, awakened as the kingdom’s strongest knight! Then, hearing those rumors, even the saint and princess came pushing their way in saying “Please train me harshly too!”…!?

This is the story of how a mere gamer, wearing the mask of the infamous demon instructor, saves dropouts while being misunderstood.
