I guess I have the roman fantasy of the metallic square scutum(?), when I did a quick read up was was made with quality layered wood and strategically placed metal trimmings and a metal boss at its center that served both in offence and defence
First thing I thought when I saw the centurion’s shield was if it was an auxilia’s shield, but it makes sense for them to have lighter equipment if they were meant to act as command officers and to inspire confidence in the ranks at crucial times
I really like how they made use of the eyes and contrast
Kamiki, losses his “darkness” to only be engulfed by it as he could not let go of his fleeting moment of brief happiness Ai brought, which ultimately became the “weight” that dragged him with the karma of his actions coming full circle.
Also how his life revolved around keeping things in place to chase a memory. It was a selfish gesture to make himself happy
Meanwhile, Aqua has two “white”, albeit fading, lights showing how he has finally found full clarity in his actions and can actually find true peace in what he achieved, his “weight” has been lifted as he can finally feel like that pit that has made his life horrible is finally gone as he frames his life away from darkness in revenge, to finding light in living for someone else.
They are both selfish, but the difference is one took life to chase happiness and the other gave their life for someone else’s happiness.
(Still feel Aqua has a good chance at living as he was floating to the surface, but who knows how it ends)
