His pursuit of perfection leads him on a journey to seek out Imperials, where he stumbles upon the renowned Hero's Imperial Holy Sword Excelia.

Recognizing his exceptional abilities, Excelia senses that Tatara is not just an ordinary swordsmith but possesses the potential to make her truly special.
