Probably discussed by some...
But what do you think happened? Did both Ein and Zwei die? Neither? One or the other?
I have mixed feelings for the ending myself. My first thought is that they both died: Reiji being shot by Elen and then Elen poisoning herself with a nightshade petal. Then I thought to myself if a single petal could kill a human and how a single shot kill Reiji after he's been shot 3 times in the chest by Sythe Master. Kinda conflicting and even after playing the game, I still am not sure what the anime is going with... ~_~
Thoughts?
EDIT: I guess a single nightshade petal can kill. Wow...
