To which my master gave a small nod. "Right. The Princess of Gold that made her debut
here was this girl. The maid Caleena, who you gave plastic surgery to. Isn't that right,
Touko Aozaki?"
Silence descended over the lobby.
Perhaps everyone was gauging the meaning of those words.
Plastic surgery. If you had said that the Princesses of Gold and Silver had undergone all
sorts of procedures over generations, carving into their minds and bodies with various
techniques in order to grasp that ultimate body, I could have understood it no problem.
But the moment you switched that word out for 'plastic surgery,' it made an impact that
was hard to describe.
"Well well," Touko laughed, clearly enjoying herself. "You think I used plastic surgery to
turn her into the Princess of Gold? While I'm flattered, unfortunately I have no memory
of doing so. Granted I don't have the best memory. Maybe I should get checked for
Alzheimer's," she said, tapping her temple with a finger.
My master took a half step back, opening a space beside Caleena's body.
"At any rate, please take a look."
"Alright, don't mind me then." Kneeling down by the body, Touko began her inspection,
looking around the lines of the cheeks and the back of the ears. "...hmm. Though
minimal, there certainly does appear to be traces of surgery. If it was done by magical
means, though it depends on the precise method used, there should only have been
indirect signs of the procedure. After all, if healing magecraft was also involved, there
would be no need for even a needle and thread. In any case, there wouldn't be enough
traces to be noticed in your everyday life."
She had no need for tools like my master did. With the air of a master who could see an
error of a single micron in the grinding of a telescope's mirrors with the naked eye, she
continued to trace various parts of the body with her finger.
After a while, she spoke again.
"Ah, seems I was mistaken. This is definitely my work."
