The anime is just too bad to view. Holy f*ck they screwed that up.
I've actually not read the manga yet, but I completed the novel, so let's see if the manga is decent enough. Thinking about perhaps re-reading the novel after this as well, was two and a half years ago when I last read it so I think I would be able to enjoy it again.
It's really a good novel, just receives too much hate because it made people expect something else. Many wanted just an edgy hateful and revenge-driven mc but got pretty much a normal mc with a slightly unusual attitude. The overall story is something I rather enjoy, easy to read and nothing that serious, just standard wish fulfillment that manages to not make me hate it.
