i'd have to go back, but with the heights stated here, the proportions seem way off :/
Edit: yeah, at 1,40m to nikka's 2,60m, there is no way that touru should be able to peak up at her skirt, he should be up to her stomach realistically.
Well, I was sure the principle was actually a giant in some way, but that she's a mountain breaking Titan was unexpected. Its pretty funny that the 'well, you could be bigger still though' fantasy was her in giga loli form.
