NOW DON'T MIND THAT 5. ITS THERE FOR A REASON AND THATS DUE TO IT BEING A VERY BLATANT COPY OF CODE GEASS.
This manga was a very quick manga that was very enjoyable as a read. it had a lot of details about everything and even little timelines and as the other review guy said, the ending was basically like as if the editor said...nope stop production.

Story- i would give it a 9/10 if not for the sudden OMG all in 2 chapter ending that this had. They developed it slow and well in the inital chapters until he escaped from the sanitorium with his "family" then it started getting faster.. not super duper but fast enough for me to notice.

Art- It uses what i call current generation manga art. you know what i mean of course. it dosen't look like Ranama 1/2 and it showed that the author and many artist helpers that drew this had a knack for tallent (just like 90% of manga out there) ...basicaklly most art will get a 9/10 from me if it's modern

Character- The characters seemed to be just dropped in and "half baked" including the main and his fiance. There isn't much if at all any development in any of them in terms of letting u feel deep within the man. this may also be due to it ending in 16 chapters. But they still are decent and u can just feel the man's masterpiece and kind of what he's been through..
any manga pulls this off these days however and u may be asking what's with the high scores for Art and Character if any manga could pull it off. well let me ask you this. if i rate it a 5 cuz every manga could do this then would you want to read it and think my review was bad??? yeah, manga's become manga's because they were able to come out on top of others.

Enjoyment- I'm giving it a good enjoyment score probably cuz i just finished reading it but yeah, it had a lot of what i expect from a good manga, all from action to the little bit of romance/ecchi ...and by little bit a couple pages. So yeah, even with the quick ending and the very bad endign itself i still got some enjoyment from it.

Overal-5/10 you may be looking at everything and think......fffffffffff what's going on. isn't there like a ....8 point something avg for the other 4!!??? well yeah. i would give it an 8/10 if this manga wasn't so shamelessly ripped off of code geass. now i have seen both seasons of code geass over 10 times, i'm a fan at heart. i went into reading this manga through Akumetsu(check it out) so i knew nothing of any similarites or were expecting any.... but i still saw them. the way the main character is such as genius at it all and his expression and deep past basically screams lelouch. his first two plans up to the sanitorium(that's not a spoiler) that might make u think..... uhhh ohh he's definnatley caugfht.....ooo wait..what???!! he planned it out :D yay.... then we bring his nemesis his sense of justice is the same as suzaku's and his last chapter dialogue with the main screams code geass. the last chapter WAS basically a remake of code geass. i can't write any spoilers here. so when u read the last chapter u will see. plus the "thing" in the background on page 25 in the last chapter... is that "thing" from code geass
Shamless too. i even went back to this page while reading to make sure what year this was published in...and of course...after code geass
