Reminded me of Volume 19, and vampires/demons in general where eye color is used to signify changes I guess. That the image of Guren above seems to have deliberately had purple as the circular background with his eyes blue must have been done to hint something - unless Asami really did just think sure let's see Guren with blue eyes XD

Whether it is something to look back on and see that it was a hint, either way as you stated yes that is a lovely image!
