This right here is why I don't even bother reading the manga... It's like they got ahold of it and tried to make it as GRIMNDARK as possible... Most of which was done through the killing of popular characters.
Even if the anime was a bit sappy with it's ending the manga didn't have to veer so far off course just for the sake of being different. I mean, seriously, Eureka, Domenic, AND Anemone? Ontop of the deaths of Charles and his wife? What the hell?!
