Some of you have probably seen that picture of the glitched/hacked Kuni customization with her mask removed, but even then her eyes are always closed. Well, I recently came across a rip of some TTT2 models. I loaded Kuni's up in a viewer, and discovered that she does infact still have eyeballs modeled under there, and yes they do have red irises.
Just a tidbit for all you Kuni-fanatics out there. I'd post an image, but i kinda had to angle the camera inside of her head to see it, so...
Yeah, they're not bright-glowing-evil-red, but still a more reddish brown than Asuka's Eyes, for example.
It's hard to tell exactly what they'd look like ingame, as this is just the raw model. Lighting, Shaders, and other ingame engine stuff effects the appearance a lot, so they might appear more distinctly one color ingame.
