The four halos above Duio's head are a result of his Sub-Specieas Balance Breaker. He gains 12 golden wings, and four halos above his head.

What sucks is that the four halos look sooo lame. The illustrator could've given them a way cooler design, instead of just lumping them together like that.

I get that he's sticking to the already established style of the halos in the series, but he could've done so much better.
