For those who are already watching Hai to Gensou no Grimgar, we all learned about the unexpected death of Manato several episodes ago. Several episodes later, Manato is still very much present in the series, in the hearts of his beloved comrades.
When it comes to death in anime, I can’t help but being reminded of the many deaths in Akame ga Kill. Unlike Grimgar, the characters in that series seem to be dying for shock value rather than as plot device. And the characters who died are easily replaced by another new member and quickly vanished from the minds of viewers.
I believe this is where Grimgar excels.
