He's an angel. The story is about how an empathic outcast with faith in people will try to treat humanity, but since this is a specific virus annihilating 90% of the population, and the main character is 1/4 person, it will be very difficult for him to do it. The halo is triangular because it emphasizes emotion. Maybe their form depends on emotions at all. If you ever want to arrange a challenge for yourself, find out about a cool competition 6 days before the end. I wanted to make a story (it sounded better in my head, ofc) with accompanying sketches, but there wasn't enough time for everything.
