You see this? The off lighting on Kaiba’s pants here? Notice how his crotch area doesn’t have that same lighting. Was it a misprint on the artist’s behalf? Why is there more wrinkles on the clothes here than anywhere else on his pants? It’s quite simple.
He’s not wearing pant boots.
He’s wearing goddamn boots that go up to his crotch. This jerk is wearing thigh boots.
Seto freaking Kaiba wears thigh high boots over his black pants.
