Okay guys, I have to be honest, from a story point of view, THIS STORY IS HIDEOUS 4 chapters in. Here's everything I found wrong just skimming this damn manga.
--------------------------------------------------
WAY TOO much exposition, the 1st chapter is basically I barf convoluted plot into your brain and acts as filler. They then spend the next 3 chapters stuffing exposition without revealing WHY I should care about the mystery, or if the mystery is important at all.
It just seems like they get drugged and dumped and that's it. It's like Lost, the TV Show, except EVERYTHING IS FILLER!! No one has any memories so no one has motivations TO ACTUALLY DO ANYTHING or GET OFF THE ISLAND so they mostly sit around TALKING and saying WE ARE HAPPY. Only the girl wants to get out, and the girl acts like a robot, spouting "I want to get off this island" every few pages and having no other motivation for what she does.
Chapter four is amazingly awful. They had the nerve to REPEAT chapter 3 from the point of view of another character, then they go into this convoluted EXPOSITION DUMP ON THE BLACKBOARD. Over Graffiti. Really? Do Real People act like that?
Did I mention they have introduced 10+ characters by the end of chapter 4 and no body has any personality and there's no character building? STOP TALKING, DO SOMETHING.
I'm gonna be brutally honest and give it a 3 star out of 10 because that's not good, it shows me the writer has nothing interesting to say and is making it up as they go, like Lost. . . . . . . and there's not enough character building and interesting action to carry the manga on it's own merit for now.
