Maybe even a movie....or a tv series
It would be a visually arresting anime not for the weak soul or faint of heart that's for sure. And little teens wouldn't be able to watch it because it would be rated TV-MA and concerned mothers and SJWs would try to get it taken down because it would be extremely controversial.
I mean there are much worse and popular anime out there. It shouldn’t be too much of a problem. I’ve never seen a manhwa be adapted into an anime before. It’s Korean
Now that it's ending I would like to sign a petition in request of turning this manga into an anime. I think that this will be awesome with moving pictures, intense voice acting, and some cool and creepy background music and that catchy opening to begin another last song syndrome. Please make this possible. Someone start a petition because I don't know how. -_-
