Unlike Overlord where Ainz just deletes enemies, or Tensura where Rimuru eats them, Lento wins by engineering.
The series follows the story of a man who, after dying in his original world, finds himself reincarnated in a fantasy world. He is reborn with memories of his past life and discovers that he has been appointed as the lord of a small territory. With his knowledge from his previous life, he sets out to develop and defend his territory, using innovative strategies and tactics.
