Japan never really thinks these things through...
(I mean, for starters, this girl would have to literally eat like a horse to keep a body that size going-- Additionally, the brain/body ratio is going to be all whack with a body like that so she is gonna be about as smart as a bag of rocks, because most of her brain would be used to produce the signals needed just to move that huge body around-- then you have the total unwieldiness of a body like that; Just think about it-- even at a full torso twist and arm extension, she wont be able to reach her hind feet, or wipe her own butt. Speaking of this latter, do you have any idea how absurd it would be to expect a toucas that big to sit on a toilet? Honestly japan--- I know you have weirdess as a social identifier, but this is just odd even by your standards.)
To be perfectly fair, all of those apply pretty much to any centaur.
This is true, but the Greek ones were blatantly magical, and so get a pass. These ones supposedly "evolved" from humans. Somehow.
So, since these are totally mundane--- again,
1) Caloric needs are off the chart compared to normal humans; would have to eat way more to stay alive.
2) normal human sized cranium + huge body == dumb as rocks.
3) Physiological inability to preform proper peri-care
4) would need special toilets/would rip a normal toilet off the wall if they sat on it/would have to flush repeatedly during elimination. (see item 1 again, combine with item 3-- wont be able to reach flush lever while sitting.)
Somehow we are expected to believe that with all these problems that would result in poor sanitation and hygiene, that these creatures would be in any way clean, smart, and attractive.....
Again, Japan, go home you are drunk.
