Reborn as a sword, I spent hundreds of years watching over countless individuals, dedicating my entire existence to guiding and nurturing them.

Then, without warning, I find myself inhabiting the body of a rough and uncultured fifteen-year-old first prince.

“Do you have any idea how many people I’ve raised?”

The undefeated great knight, the dragon slayer who once brought down the mad dragon, the mercenary king—and many more legends—I was the one who guided them all.

Now, the Magic Sword Gruhorn has taken over the body of the unruly first prince and begins to carve out a new legend of its own.
