Yeah, see, I pulled Irene specifically after two events in her gacha game featuring her and the region she's from in general, in which she has to deal with talking aquatic creatures trying to eat/assimilate her. "It'll be fine," I said. "She'll probably have a few months to gather CR before this sea thing becomes relevant, if it does," I said.

And then I saw this event. I laughed.

Anyway, let's do this. It'll be pretty easy to justify her heading out there in general (curiosity, investigating threats before they go after people, etc al), and I made sure to have her sans weapons for now so we don't have to worry about a floating selkie corpse, but she might need Tsubaki to keep her from instinctively trying to smack a kelpie (or whatever) in the face with a rowboat paddle.
