Fauna has the most fanservicey outfit. Her boobs are more exposed, her feet are exposed, and she has one totally bare leg and one thigh-high. Mumei's outfit was mostly just cute. The most erotic things about it was her one bare thigh and her smaller boob window.

Emomumei however is pure sex. Mumei also has the most erotic body. Medium is premium + widest pear in Hololive is a lethal combination.
