If I had to sum up this manga in one word it would be "disappointing." The story starts out interestingly enough with a sex-change and some really competative guys, but by the end it was clear that the author dropped the project way before they meant to. The last two chapters skipped two years of what could have been really great character development and creates to scenes that left me feeling like they needed an extra chapter to complete the thought. Overall it left me confused, mad and wishing I had never picked it up in the first place. Whatever enjoyment I got out of the first few chapters was ruined by a poorly concived attempt at a last minute ending. My advice would be to avoid reading it all together.
(Please note that this review is based only on my enjoyment of the manga and not on any real knowledge I have on manga as an art form. Thank you.)
