love this!! It was really cool how everything connected in the end xD Yeahh, in the beginning it was kinda wierd and confucing but it got better (which was good..) During the middle it got kinda boring tho.. but the ending was AWESOME! :D totally loved it! However.. i felt that in the beginning it seemed as though Hikaru ( i think that was his name ;3) liked/loved Ruika because of what she will be i the future..like he didn't really see the ruika that was there. But all was good ;D not to mentioned the art got better near the ending. xD Trust me the beginning's art was TERRIBLE ! xD LOL. Ruika looked terrible in the beginning, but then she became soo beautiful during the end of the story; Hikaru looked horribel too..i tohught i was going to puke when i saw him in the beginning xD ><" but he got wayy better and HOT in the endd!! LOL.(meaning the art changed drastically) i had thought of giving up on this manga.. but good thing i didn't xD Hee, Well anyway i love te ending!! ;D esplly how Robin became their son :3 <33 I thought i was going to cry when i thought Hikaru was seriously dead..BUT ofc that won't happen x3 everything was good, but the only thing was.. that i wanted to know if Ruika still had her power in the end...><"" and i wanted to know wut happened to Sissy and Haruhi...-sigh- well i'm going to give it a 9.5. And the missing 0.5 was b/c of all the unanswered questions i had and b/c of the beginning xDD LOL. well GO AND READ THIS MANGA NOWW! xD just make sure to stay with it till the end.... that's when the REALLY good part comess xDD LOl.
i really think this might go in my top 5 just having a hard decision which to replace..
but seriously the storyline, plot art everything was just briliant, it kinda has a little off moments but all in all its brilliant i love how they used science and made in fiction from fact to fiction
i hope this gets licensed coz i really want it in my manga collection
I'm loving this way too much. I was kinda wary of reading it first [because the mangaka of this is the same mangaka of Please Save my Earth, which I HATED] but I decided to give it a try. It's amazing! Can't wait for more releases, I'll update this comment when I've read more.
i really liked this story and i love the main character. i still can't figure out the blonde dude though...it's kinda a complicated love maybe? i love the girl's hair when she looks like a goddess (;
the art is beautiful and the storyline is pretty unique. however, releases are so slow that i always forget little details about the story >_<
