#he prolly jus has somewhat of a harder time processing and portraying proper emotion compared to the average person

i used to be all for illumis eyes being that way becos overtime as he had to endure more and more torture his eyes jus became completely lifeless and thats y theyre devoid of any color and all black n shit. but i came to the conclusion that that could jus be his thousand yard stare from everything hes had to endure. not that his eyes had "lost all color and life" sorta thing.

its evident that millukis eyes are also as black as his, so the black eyes are definitely a genetic thing (probs from kikyo) but i think the reason illu looks like *that* is jus a case of thousand yard stare from being traumatized beyond belief, and the black eyes jus kinda add onto it. and maybe thats y hes so fucked up compared to the rest of the zoldyck children.
