Oh look Raine's gotten a spot of development again!
This might take a little explaining. So, Okimiyage has swirl tattoos on her arms, which glow very brightly in situations of extreme stress. They give off an extremely bright flash of light when this starts. Raine and Moon had been tagging along with her at a time when it was dark, and Okimi got stressed out...Moon was smart enough to look away, but Raine was caught completely unaware. As a result, the flash of light blinded him. He was left staggering in pitch darkness, unable to see where his friends had gone.
He's recovered his eyesight nowadays...mostly. He needs glasses now. His vision is badly blurred without them.
