There's a moment or so where Inigo is thinking about that answer, mentally chewing on it as he considers it. It's very much like Roland, not wanting to draw too much attention to himself, right? Or at the very least not wanting people to go out of their way for him, instead prefering to be the one going out of his way for others.

It's hard for Inigo to fully grasp the importance of birthday parties, also having a hard time even remembering the last time he celebrated his own, but people here on the train sure seems to care about them, if this whole big party for Senku is any indication. Gen even going out of his way to calculate when Senku's birthday on the train would be...

For - luckily for Roland? - Inigo is dragged straight out of that train of thought by the question.

"Oh.. August 7th."

Isn't Roland a lucky dad. Getting a straight, honest answer through catching Inigo off guard like this. And it's in normal Earth terms too! Apparently it's one of the few things Ylisse actually shares with the modern day world.

Inigo is already hard at work folding another star, if not just because he now wants to absolutely shower his higgledy in them. She seems to be having so much fun with something so simple.

"In the middle of the summer."
