I like numbers. FAIRLY WARNED, BE YE!
Many Anime figures are scaled, by which I mean they say right on the box what scale they are relative to how big the actual character would be. Commonly, this will be 1:7 scale or smaller, but the point I'm getting to is that I have actually seen 1:4 scale figures that, in theory, would be similar in size to Grace in this comic.
They're. So. SMALL!
Well, sort of. Relative to other figures, they're absolutely enormous. In terms of volume, however, they're 1.5625% of what they'd be at 1:1 scale. Things are 64 times as big as normal relative to Grace now, except for Ashley, who is a mere 8 times as big as normal relative to Grace.
Tiny. Tiny Grace.
