Basically, I prefer not to comment to any manga that still has few chapters. But hey, this manga is the first rank in series stat in 1 oct 2013 (the day i wrote this review). So, I will give this special manga with "special" treatment.
First of all, I can feel the "shounen" aroma just looking at the first few pages in the first chapter, and I personally don't like it. Well, it because usually that kind of manga have a damn straight plot story without any deep story development, just like MAR manga (my apology for MAR fans).
For the second comment and so on, I will try to write it after looking at the development of the story... and I have read till 36, so here is my conclusion so far:
Plot: Yes, its damn straight shounen, my gut feeling tells me right. Hard boiled character, sudden-power-ups, black n white opposition who has potential to be friend, n etc. (you can mention the others by your-selves). And yeah, the story is still weak, too straight (so far)... no strong emotion that I can feel (still few chapters maybe)
Art: Im impressed by the battle scene, really... even though I can guess who will be the winner easily, but the battle is conducted really well (remind me Onepunch-man), and its a big plus.especially when the battle began... oh, the fanservice too, it is nice (not excessive)...
Character: Tsundere... is the best sweetener of romance... other than that... just ordinary.
My rate: 7, I guess
