Yup. The japanese commentary outright references Revenge of the Sith.

Here it is (DeepL, edited by me) (knew this was a reference):
"I've been trained in your Gensokyan swordarts by White Wolf Tengu! (likely Momiji, commenter's note)
Shortly after, she loses two of the arms."

I hope the robotic ones were cut.
