I think this is one of my guilty pleasures. It's one of those comics which is so bad, that it becomes good. Sure the art isn't great, and the source of the story, as has been stated by many, is ripped off from Angel Densetsu.
HOWEVER, having said that, ** I found this story to be much more addicting than it's manga counterpart **. I actually really love how Ingong isn't a complete douchebag who's naive - he's pretty manipulative. He's not perfect, which I find really refreshing, because too often, like in Angel Densetsu, the male protagonists are cookie-cutter perfect beings or completely evil beings. Ingong's a coward, and proud to be one! xD The creativity in the situations is amazing (I found this to be better than Angel Densetsu in this sense), and man oh man, did this make me laugh. I was literally crying over my computer, because of all the laughing.
Overall, I really loved it. I mean it's not perfect, and the art starts out kinda crappy. The characters are fairly endearing, and the story grows on you after a while. And if you're looking for a laugh, this one is perfect for you. WHEN READING JUST FORGET ABOUT ANGEL DENSETSU. Seriously, just go in with no expectations like I did, and you'll probably enjoy what you come out with.
