Mogeko Angel Halos can be taken off randomly
Yeah, I double checked with the other side. Turns out that someone in the wodagrora cult over there asked about Grora’s halo since she had it during the war but doesn’t have it now, and the response was,
The halo is merely an equippable ornament, and can be removed at free will
So there you have it. The Mogelympics not only have scarf wrestling competitions, but also halo frisbee knockout competitions.
