Along with Tia and Aurora, Ars will be showing up in some flashbacks scenes from when the three of them were kids.  So, here’s an image of him as a child.  Even as a kid, he was deeply in love with Tia, though it wouldn’t be until several years later that he found the courage to confess his feelings.

Note that, just like with the image of young Aurora, this one isn’t quite final as the wings still need to be added.
