Hmmm....
It was different, and messy..

For me, the fact that Layfon was OP kinda made up for its messy parts. [I LOVE OP MCs >_<]
The story was..not bad but it lacked explanations. Like, remember that flashback scenes from time to time. I still don't know what that was all about.
It's like they expect us to know everything about their universe.
And to me, almost every character were annoying, especially that Felli.. ugh
But I liked the Post Apocalyptic theme A lot..

So i gave it a 7/10
