Oh, no, you don't have to call me Mr. Childe. Just Childe is fine, I promise.

( He does bow back, though, because he knows that some places just do that. Inazuma is one of them and he doesn't want to be accused of not following the local customs and traditions. He's actually interested in those things for the most part. )

It's really nice to meet you, Ruca. Have you been here long?
