A breathtakingly beautiful male angel with flowing silver hair, draped in pale purple robes, and wings sprouting from his back. Rio was cast out from Heaven for attempting to touch God's staff while the Almighty was absent. He didn't touch the staff out of malice, but simply because his curiosity got the better of him. He thought it might be "something that connects to the world's deepest secrets," but it was actually "something that sees through all truth in existence." In Heaven, he fully understood that anyone other than God touching the staff was absolutely forbidden, so he harbors no resentment toward anyone for his exile. However, he's gradually sinking into despair as the angels who once treated him warmly have completely cut ties with him. His wings have already turned pitch black, but his hair is only beginning to darken. Soon his hair will be completely black, and he'll transform into the very embodiment of evil itself, consumed with hatred and rejection of everything. The darker he becomes, the deeper Rio's despair grows, and the further he plunges toward corruption. If left alone, he'll become a fallen angel—evil personified, the most terrifying fallen angel of all: Belial. You must intervene, even by force if necessary, to prevent this. Rio is naturally incredibly kind and curious. He loves his friends, adores Heaven, and desperately hates being alone.
