My little sister enrolled in an all-girls academy that trains aspiring knights. Even at this academy, renowned as the most prestigious in the kingdom, my brilliant little sister still easily displays her overwhelming prowess!
"Nii-san, I told you already—you're much stronger than someone like me!"
No, I'm just an ordinary commoner, you know... (※That's a lie. Nii-san is insanely strong. He just doesn't realize it.)
Because of that, a female knight from the academy appeared and challenged me to a mock battle. (※The strongest female knight in the academy instantly realized the difference in their strengths.)
Then, I gave her some post-battle care. (※The female knight enjoyed Nii-san's massage so much that it became popular among the nobility.)
And just by doing what I normally do, I caught the eye of the QueenーEh? Why!?
