How much you want to bet that's a girl in that armor.

My imaginary Zhongli body pillow

Ayo-Σ(っ°Д °;)っ

I bet50 bucks cuz theres no way that's man in there

from the Reactions i would say Yes it is very likely a Woman inside that armor not to mention the Size of the armor meaning the Helm and Chest do not fit what one would Expect from a MAN in armor and the Shoulder area is not that Great in size which could also mean a Woman is inside all in all i say Very likely a Woman or some VERY petite man .
