Chapter 1641: The Second—"Irena, You've Done Something Huge!"
Reines: ???
Reines looked at Islo before her, then turned to look at Irena.
She suddenly recalled what her brother had said before.
To verify whether Irena truly possessed beauty comparable to the Gold Princess and the Silver Princess was actually very simple: just have Irena put on the Gold Princess's clothes.
"—You're not joking?" Reines asked.
"Mm." Islo nodded. "My abilities as a tailor have been deeply influenced by their beauty. That is why I've been able to improve so remarkably."
Reines knew that the "improvement" Islo spoke of was probably not merely his ability as a fashion designer, but his ability as a magus. The gowns worn by the Gold Princess and the Silver Princess likely also served as Mystic Codes.
Or rather, their clothes themselves were Mystic Codes.
"D-Don't misunderstand!" As though he had seen through Reines's thoughts, Islo hurriedly clarified. "The clothes I made for them aren't the kind of Mystic Codes used to display magical power and trigger phenomena. They are simply clothes made to bring out their beauty."
"'Looking at beautiful things makes one beautiful'... is that it?" Reines gradually understood everything.
The other party did not create things through magecraft, but was obsessed with "beauty."
The purpose of making those clothes was beauty itself.
—Perhaps every member of the Iselma Family possessed this trait.
"You have a good eye! I'm beautiful on the inside."
Irena was extremely pleased at this moment, her tail practically sticking up into the sky.
"Wait, are you really sure?" Reines asked Islo for confirmation
