To the guest, how left me the review because you don't have an account, I'll answer your questions here hopefully you'll read this. This may also answer some questions on chapter 2 for some of you.
First as mentioned before this is not a traditional haram, this story will revive around many girls including a female Yuno who has feelings for Asta but puts their rivalry first. As Asta is in cannon he will be blindsided to their emotions by his devotion to Sister Lili, just with a group of girls instead of the traditional three.
Second, regarding the changes go Astas Anti-Magic, for those worried he will still have his anti sword don't worry but as some of you have noticed or read Asta already had his anti-magic before getting his grimoire. In the beginning, it shows that Asta is strangely resistant to magic, on his own he has some resisters to magic with some mana detection spells being canceled when used on him. The grimoire works to evolve his anti-magic it does so by giving him the effects of his other swords but before he can use them the grimoire gives him an item to use the effects through that he must master to learned to use the other effects on his own. The first one will be his sword but some ability will get other items. He will also gain some new effects, not in cannon.
Finally, Asta will be getting a new ability than in cannon. As he gets better at using his anti-magic he will develop something I'm calling Anti creation magic. His equivalent to creation magic, when he fully masters the item that the Grimoire gave him he will be able to create any item with whatever effect he wants, but he won't figure this out till later chapters.
Also for those wondering who the scavenging vultures are. think of them as mana thieves, that's all I'm saying for now thank you.
See you in chapter 3
