That's the fun part: we don't really know.
It's very likely that she will be a rushdown, not an outright shoto. We didn't have a real rushdown in a long time.
The shark arm is still a big mystery box. Concept art shows using it to shoot lasers (or water beams). In the gacha, it also gets giant and noms the enemy. I myself hope that she has some set-play going on, summoning whirlpools and that kind of stuff. Or setting up the shark as a trap.
