Aki is shown with one wing on the cover of volume three, which is actually titled One Wing in the Viewfinder. There's another illustration of him with two white wings where he's holding an arrow pointed at Asami's heart. I couldn't find the full illustration on this site. Part of it is used as the cover of the Finder Character Book, but you can't see the wings. So yeah, I think it's symbolic as to how Yamane Ayano views Aki's role in the story.

I never saw this cover before. A rare sight.
At first I thought, 'this is Aki and Asami, right?!'
Aki's got angel wings and Asami's got a baby in his arms. xD
I love the determination in Aki's eyes and how he is protective of Asami.
