I mean, again, they're all capable fighters because they need to be for the game to work. But that doesn't mean it's their jobs. Even in Inazuma. Ayaka, Ayato, Thoma, Yoimiya, Itto, Shinobu, Miko and arguably Kokomi and the Shogun don't really have jobs that require them to participate in any sort of regular combat. They just happen to all be vision bearers skilled with weapons.
I could see it as a thing you have to run from/avoid in certain places maybe. Given that we can't fight back in the water though, I'm not sure I see it being a huge part of the gameplay even if they did do something like that.
