Needless to say that manga is 99999999 times better than the adaptation. And this ending is pretty bright and touching.
Isn't it?
I love the fact Kouta doesn't forgive her so easily in the manga too, and actually got pretty close to pure hate. That is how I would react if someone killed me family members too, I wouldn't want to be friends with that person for sure.
Another thing is inconsistency in the anime with the manga. The anime shows Lucy as a fairly weak Diclonius for the original. I would expect her to at least kill Mariko but she got pounded in the anime fairly badly. Lucy is a psychopath in the manga, I like that. Also, Nana is badass in the manga, and purple hair suits her far more than bright pink. Progression is also handled better in the manga with less "Forceful" plot turns.
Anime nailed the atmosphere with the music/sound effects though. If it was extended to 24-36 episodes I imagine it could have been much better.
