Discussion Ancient Spell

Celestial spirit magic isn't ancient however it's really rare because now there is only two people that use it

I think I said this before but I find lost/ancient spells to be overrated. Hiro Mashima introduce some spells as lost or ancient just to make it sound like they have an extra punch.
Most should be lost because they failed to stand the test of time.
