Why do Asagi's eyes change color? Normally, Asagi seems to have reddish-orange eyes, but under certain circumstances they change to a bright red color. This happens, for instance, when she is hacking into the Nalakuvera. The change is a bit subtle and I'm not even sure if it's intended or if it's just a combination of different lighting and inconsistent animation, but it is at least noticeable. Here's a comparison shot with the two most extreme examples I could find:



Is this change actually occurring or is it an animation error? If it is real, what is the meaning behind her eyes changing color?
There is nothing wrong there. Her eyes are red, and because of the sun, they look reddish-orange. Here is a link that will tell you everything about her:  http://strike-the-blood.wikia.com/wiki/Asagi_Aiba

On that site, it says her eyes are red.
