Reborn as a sword, I lived for several hundred years, spending my entire existence looking after everyone. Then, out of nowhere, I took over the body of a fifteen-year-old uncouth first prince. "**Do you have any idea how many I've raised?**" The great knight once called the **Undefeated**, the **Dragon Slayer** who brought down the **Mad Dragon**, the ***Mercenary King***, and more... I raised every single one of them. The ***Magic Sword Gruhorn*** possessed the body of the uncouth first prince...And has begun to write a new legend.
