I’m an Introvert Who Became the Body Double for the Unrivaled Sword Saint, But the World’s Strongest Seven Swords Prefer Me Anyway

Synopsis

Introverted engineer Kaito is suddenly summoned to a fantasy world. There, a lovely Hero Princess asks him to act as a body double for the realm’s Sword Saint—a man who happens to be his spitting image.

Reasoning that he’ll accept as long as he doesn’t actually have to fight, Kaito reluctantly takes the job. However, his professional habits as a system engineer get the better of him, and he can’t help offering meticulous support and thoughtful accommodations.

The soldiers—who had been relentlessly overworked and berated by the brutal original Sword Saint—are deeply moved by his kindness! On top of that, with a spirit’s help, his bizarre tactic of turning monsters into edible rations becomes a massive hit.

Kaito just wanted to spend his time safely in the rear guard, but before he knows it, he’s being hoisted up as a hero by his soldiers—and even by the beautiful girls of the Seven Swords on the front lines!
