You shouldn't expect much from the promo. The summary is great and the art is great so we would normally think the manga would be the same. Sadly, authors put alot of effort in promos but not the chapters since you have to continue writing the same art but promos is a one time thing.
I do see ur point. But I think that for people who actually buy this. After having looked at the promo to get what we have now I mean .. I would be upset because its false advertising in a way. I know I can't talk since I'm not spending my own money. However if I was I'd be disappointed.
Yeah imma drop this. The story is kinda boring and I was really looking forward to it from the promo art. And then u see chapter one and u think .. hold up is this really the right story?! Then u read alittle more and it is and that's just .. disappointing (╯°Д °)╯╧╧
