There have really only been two people, his entire life, that Galliard has allowed to call him Porco. The first was Marcel, and the second Pieck. Anyone else who tried it tended to have a snarling ball of rage on their hands immediately after any attempt, and there was usually only one attempt.

"I have no idea."

He's gotten so used to being Galliard that the thought of having an actual first name isn't something he's ever considered. It's not like Eldians are allowed to do such things; he just barely got away with being called Galliard in the military.

He chuckles at her suggestion, though. "No, probably not. That one's just for you."

That one and Porco, or Pock. Privileges only Pieck is allowed.
