Hey, a greeting is a greeting, and it's rude not to reciprocate. Ebisu waves back, still burning with curiosity as ever even if his shinki seem a little wary. After all, if he was going to get hurt, doesn't it seem like it would have happened a lot sooner than this? As it is, giving away something like this almost seems like dropping an ace out of your sleeve.

So, instead, he asks, "Is it alright if I touch you, Minion-san?"

Because he needs to. For science. Is it a solid entity like his shinki are? Will it fall apart if he presses too hard? All these questions and more bubble inside his head.
