Why is no one mentioning that we finally found out who Asta's Grimmoire belongs to ..
Its LICHT's
Or was it revealed earlier ?
I suppose that's because it was pretty much confirmed when we saw Pattolie/fake-licht's flashback, revealing that Licht was the popular elf leader and was using sword magic.
Among other things we know that grimoire had only four leaves when when Licht was alive. So, the fifth leaf was probably added when he evoked the forbidden reincarnation magic and properties changed.
I wish to confirm whether his sword magic was different than Asta's anti-magic or it's just that elves called it from a different name back then. There is some translation difference in VIz verson and ********* etc. Grimoires probably choose people according to their mana level and latent capacity and thus Patollie probably chose people based on their matching grimoire magic. In that case Licht should be able to use the grimoire and anti-magic without being affected by it's anti-magic properties.(either due to too much mana or it not having an effect on him to begin with being his swords originally)
