To be fair shizuna is debatably the strongest swordsman on the conitent having cut early 1208 reans tachi in half with minimal effort soooo I don’t know what you were expecting for her to play nice and all
Play nice? For me it felt like she was a glorified training dummy! Honestly a very underwhelming boss fight with how easy it was; though that basically extends to the entire game sadly. :(
