Well, Shushu likes wrestling and can also shrink. If you're still not sold on that, you can also alternatively use Himari since she's like the Megaman of the series and can work as a stand-in. Himari can turn her body parts into weapons and other equipments, turn someone into her slave which transformers them into a demon, and I think in the manga, she also learns her sister's time-stopping ability. It'd also be interesting to play her as the copycat fighter.
