Why Am I the Younger Brother Among the Seven Saintesses?

Me: I've spent three years traveling abroad, and I know a thing or two about military affairs and economics.

Saintess: But you're a little brother.

Me: I'm well versed in making distant alliances and attacking nearby enemies, and I can unite the entire continent's forces.

Saintess: But you're a little brother.

Me: Can we stop talking about me being a little brother?

Saintess: But you're a saintess, too!

Me: ...Let's go back to me being a little brother.
