Apart from the action, and amazing well-drawn fighting scene. This manga also has an interesting love story, a good sense of humour, and uh a lot of nudity which done pretty decent (although some might be considered misogynistic in a way).

All of the character (main and supporting) have some kind of tragic background that made you want to read more and more, my favourite would be the butterfly duo. Another thing about the story is how the author divided two stories of the main and supporting, gradually building them up then connect the dots at one point.

Overall, it's a pretty good manga, looking forward to the climax, and hoping it has 200+ chapters or 300+ would be nice.
