After finding out about Megiculas curse on Lolopechka, I am still very surprised that Asta never tried to nullify it with anti-magic. After all, curses are just spells with lingering effects, and it's been shown that the demon destroyer blade that Asta possesses is capable of absorbing and nullifying magic, even the ones with long lasting effects.
So how come he's not tried to dispel the curse, especially since it chirping off her life force drastically?
