So, we get our main character who keeps a secret superhero identity (Batman, no question) and works outside the law. He is rich, lives in a HUGE mansion, works as the boss for some sort of company, and he does this (and his superhero gig) because "its the family business". Not to mention, he only lives with ONE butler (who can to everything, despite his really old age) and nephew who is over-protective of his Uncle (Batman).
Sound familiar yet? Yeah, then in comes the bad guy, our superhero's love interest. Not only is he the "enemy" but he's also working for a bad organization trying to get their hands on a rare set of paintings. As with any romance story, we all know that the bad guy really isn't "so bad", and the two fall in love "at first sight" while unknowingly meeting each other "out of costume".
It felt dragged out, rushed and so littered with clichéd plots and characters that nothing will be new, surprising or even interesting. The storyline is beyond overused - it's like watching a remake of a movie, except the only difference would be that the "girl" is a "guy".
While this manga is a good read for those wanting a "superhero" themed yaoi (since they are so rare to come by), everyone else might just want to pass this up. As much as I would like to see a "gay Batman" (the idea sounds really exciting in theory) - this book follows the used "batman" story line so well, its rather disappointing. So, read it if you must, just don't go into this with high expectations. Like I said, it doesn't even TRY to be different, beyond the "Batman's love interest is a guy" statement. But... it gets a 5 for trying.
