I just want to clarify things. Asta's grimoire is from Licht who uses Sword Magic. And I thought that he can't use the spells in the grimoire since he doesn't have mana. Then, why didn't the demon swords disappear when Licht died? Ares they physical swords and Licht used his magic to amplify its power? If so I believe that the demon channels it's anti-magic to the swords. After all, Asta used Yami's katana to defeat the enemy (I forgot the name hehe). After I saw that panel, I imagined Asta using different weapons and infusing anti-magic in them i.e. Bows and arrows, spear, etc.
