hmmmmmm
i'm like 90% sure they're gonna reveal the demon as his pops, the other 10% is that the author's deliberately setting up that assumption to break it down later.
Was that Asta's mom there at the end? Or at least an ancestor or something? 😳
And I really like Asta's standpoint of not necessarily being evil just for being a devil.
i think asta is a hybrid like charmy so half human half devil and was born like rin and yukio from blue exorcist so his mother was posessed by the amd got pregnant and asta was born
99% this devil is asta's father which would explain why he has no magic at all since this dude's power is anti magic so the magic within asta got erased
