Deepest lore: students perceive halos as a normal ring (like Mob-chans), but to Sensei, they take on unique shapes

I don't think it's been made clear if students can even see halos at all. They know that their halos exist, but they might be totally invisible.

Well, they do have to be able to see it some way or another, halos being broken is kind of a huge deal in the lore. If they know it breaks, then they see something at least.
