Three attributes pants have I never knew about.
- They apparently make you cool. Somehow.
- They are addicting.
- They generate a barrier that doesn't allow skirt peasants to even come close. For only other followers of the pants master race may engage in yuri with them.
I know Japan's strict about school uniforms, but are you telling me these girls don't wear pants at home sometimes? Not even hotpants? Pajama pants? Yoga pants? Jeans?
Pants for girls exist, obviously, but the thing is that it's a cool skirting(ha!)-the-rules kind of thing. Yes, you're wearing an approved school uniform- just not the one typically designated for girls (or a conformist one, in an all-girls school). The anti-conformity thing is that much more pronounced in Japan, whose society has so much conformity that any deviation from the rules stands out enormously, and as a teenager, standing out in a cool way is H O T.
As for the anti-skirt barrier, imagine it from that angle. The two unbelievably hot kids are flirting. You know you have zero chance, and you give them your space.
