(Spoilers,and not really a headcanon)
In the credits it showed that all the kids are alive,the others I can understand but how did nagisa survive being crushed by that robot?
Would be nice if someone could explain! :p(Edit)
Been thinking, the picture in the credits couldent be in the 'afterlife' as kotoko is there, unless she comitted sucide.
(I honestly wouldent be suprised seeing how dark another episode is)
