Honestly the manga is better, if I had to follow only one, I'd drop the anime. Even if it keeps having a two month lead over the manga. The stuff that's weird in the anime makes so much more sense in the manga.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
