Just recently finished the anime and I loved it so I decided to read the manga. Here’s my theory on why they seem to have similarities but drastic differences in arcs and events. Not a crazy idea but reading the manga it seemed that this in itself was a different world. Since at the end of the anime it is told that they get reborn (and eventually will meet each other again and need to find paradise) then the manga isn’t an adaptation from the anime but instead showing a different universe/world of everyone being reborn. Which makes sense why there is a different ending and outcome.
