Overall I was okay with how they showed Akise's death. In the manga they showed his thought process with images for his last deduction about Yuno, and straight up showed the audience exactly who the fake Yuno is. I think I prefer how the anime is handling it, I just hope that iconic image that revealed her identity is still shown as a sort of flashback or something.
Though I'm sad we didn't get to see the full view of his headless body walking forward. It was a powerful image in the manga.
Here's what it looked like in the manga, if you want to see the gore before the blu-rays come out.
And with that, the 17th Angel-I mean-Akise Aru is dead.
