Its called being good at drawing.
It's usually a real life photo that gets put trough a photo effect that makes it look like a drawing, a lot of artists use it because drawing backgrounds take too long. This manga had this kinda backgrounds way before AI was this popular.
Dumbass, loud and wrong
If you’re gonna accuse someone of using ai then you might as well accuse every single artist. I’ve been reading these since release and its not the case for this artist. They’ve literally been showing proof of their art style. Either read from the start or look up the artist instagram and other social media platforms.
You’re the one who’s wrong and dumb. Go look up their social media.
You all are stupid or blind I love this author and their artstyle but its hard to not to notic the background being ai generated just look at the recent chapter and stop being so fucking naive you stupid motherfucker
The background being mostly ai generated is so fucking ironic
