I'm writing this while watching a TV series on Hulu so don't expect much.
Story: 10. Barring the ending the story was executed well and the plot moved smoothly from one climax to the next. Rei - Zero twist was confusing but interesting
Art: 7. Art was amazing save for one thing. What the fuck does Kurohime look like?! She fucking looks different EVERY CHAPTER. It's not that she doesn't look better (in the beginning she looks more like a 70's w**** compared to a badass sorcerer or whatever) but the inconsistency takes away from the story. Otherwise art would be a 10
Character: 10. Character was amazing. I tend to look for a specific thing in romance manga. This "thing" is attraction to female lead, it sounds weird but in manga like Bakemonogatari male readers feel emotional attraction to Senjougahara, i'm not talking bout love or anything, but it's definitely noticeable. When I feel that I know shits gonna be good. Kurohime was like that. (Fuck the ending)
Enjoyment: Plot kept me on my toes, art was nice, character development was great. Enjoyment = 10
Overall: 9. Here's were I bitch about the ending. What the fuck?....fuck?.....whaaat? This shit almost ruined the manga for me. If their gonna have JUST 1 genderbender tranny shit I want to know in the tags. The only reason why this was dropped 1 point is because 8 does not do justice to the rest of the story. But please.....
