Man this manga is just plain awesome. I relate to those people who thinks that the manga at first when looking at the cover would be like pretty general romance manga, like what i initially thought of somewhat similar to Ah! My Goddess! which of course i love both manga and anime. So i decided to read this manga, and man was i surprised! For the better that is, since it is actually more serious than i thought, at first I thought it was a general theme that the weak main character will become strong to protect the girl, but then the moment the hero who imagined his fairy tale just went down the drain and that the world he was going into was more like Hell, man was i HOOKED!
Also this manga has sooo much things to cover that has left untold, like Haruna and Lilu's past (why Lilu got betrayed), why Shinya's classmate (the girl named Akie) also felt Shinya's presence when he almost died, Hime's past, the mystery of Taru Taru (Since she seems a lot powerful that she lets on), the truth behind the books and the destruction of the world, the mystery of Shinya's teacher lol (maybe a side story of the guy would be for laughs) and what is going to happen with Shinya's harem?!
I hope he would still have Lilu with him in the end, since she is likely to be the one to be separated. Since it also implies that Lilu is a main character as Haruna, since they did meet at the same place and the same feeling Shinya felt with the both of them. What can i say, I am more of a Lilu fan than Haruna's since her past and disposition is quite tragic.
I still hope they manage to stay together and all live happily in the end somehow. I truly hope that the story would have common theme that the hero will win and everyone is saved and stays together. Well what can I say? I'm a sucker for heart warming, live happily ever after ending, i mean staying with all of them was Shinya's dream after all.
PS: Sorry if I mentioned any spoilers, since there seems to be no spoilers tag.
