>>657887I found a better picture of Nyanners, without the hat and facing forward, and her head-to-body ratio is the about the same as Polka's. Also consider that I measured Nene's height from the very bottom of her avatar because her heels aren't visible, so her ratio is likely a bit lower than what I actually wrote it down as.
Either way, the general point still stands; if Nene and Polka aren't lolis (and I've never seen anyone say that they are) and their head-to-body ratios are roughly the same as Nyanners's, then Nyanners's ratio can't be used as proof of her being a loli.
