The incest is kinda like "My brother/sister is the only reason I exist", kinda like Yosuga no Sora. As for the cannibalism, it's very graphic, it's 'I can see the intestines' graphic. Don't worry, I'm sure it will be censored in the anime. Hopefully not
If the incest thing isn't even that good then there is no point in trying to force myself to watch it.
i had to read the manga (the parts after the anime ended), makes the whole story better. better yet just read the last 5 chapters of the manga
Thats what i did a few years ago too. I wanted to see the differences because the manga was a huge let down (mostly because i wanted to see the second season) when it came to endings. But the anime was even worse and it didnt even made sense.
