They supposed reason Haru survies is that the world brought him back as a reward for saving hit. Normally I wouuld have no problem with kinda thing since the foundation of Shounen is happy endings and all that. HOWEVER given that the world had constantly fucked over the
Raregroove family that created it in the first place it seems more like the world iis/was just being arbitrary.

First, I feel like spoiling a plot twist in your title is kinda annoying. I read Rave around when it first came out and I would've been very annoyed had I read your post title. Spoilers are expected for old stories, sure, but people come here to find manga to read. It's not like mentioning

L dies on an unrelated Disqus comment.

Second, the whole point of the entire manga was that the world was being corrupted by evil. Bringing him back was the least the world could do to make up for all the sh!t they suffered through on top of saving the world from becoming fully corrupted. How exactly do you do you read a manga and miss the central plotline?!

Seriously, wtf. I'm reporting this thread because it's the biggest pile of garbage I've read so far this month.

Really? If the world was overrun by anything I got the impression that it was overrun by sorrow.
