It's 更多 of a action/comedy then romance, even though there is some romance.
I found it really, really good myself, but it all depends on your 日本动漫 taste. If 你 like guns, assassins, violence, murder 或者 anything like that; I'd suggest checking it out.
There's a lot of comedy in the series and a little bit of romance. :)
Personally, I think that it's a pretty good series, in terms of how the plot and the factor of enjoyment was executed, but nothing special. It is fun. =)
