Yotsuyu is not cowed. She may be the last of the Naeuri clan, but she is a better bearer of such than ever her unlamented brother was. She stares coolly at the young man.

"As a matter of fact, I am." Never mind that she has an Oshawott in one arm. Lusamine took her in, certainly there's enough room for another put-out Pokemon. She lets Gosetsu down and gives him a pat on his head gently. That's encouragement for him to go play nicely with the others. Maybe he'll find a friend?

"So. What must I do?" Since Yotsuyu is not inclined to prance in, declare that she's with the Aether Corporation, and here to take one of the displaced Pokemon home. Even though that is exactly the case.
