I dunno. Having read this and done s scan online explaining the story it makes sense. But the artwork was really vague, I couldn't ground myself in any time period and the lack of chronological story was bad too. Really I don't get this story, and while the artwork certainly is unique I'd have preferred something simpler like The World of Narue. Nor do I get why Naota fell in love with Haruka and not Eri, who also has some parasite in her head and likes him anyways. I'll need to see if I buy the manga.
6/10.
