Raising the Northern Grand Duchy as a Max-Level All-Master

Unlike the previous time when Sigma had invaded the factory, Arina, now disguised as Mary, was fighting with her full power, revealing her complete abilities without restraint.

“Good heavens… Lady Mary is a Sword Master?!”

Knights watching the duel murmured in awe.

Her display of strength, on par with the highest-ranking knights, was already astonishing. But now, she was going all out, fully demonstrating the prowess of a Sword Master.

“And that swordsmanship…!”

“That’s the secret technique of the Grand Duke… no, the royal family!”

“It’s identical to the swordsmanship of the late Grand Duke.”

“Did they pass on the same techniques and mana training to the illegitimate child?”

“With talent like that, it’s no wonder they did.”
