One of those hilarious and a bit lifeless anime/manga (s). May be just me, but I think this manga is in the genres: Action, comedy, shoujo and supernatural.
Of course, there is romance, but in a different way. Harem is also another.

The hilarious and a bit lifeless part from my definition is a bit like Zetsuen no Tempest or Hatenkou Yuugi. Where "Life" itself has a certain importance.

Generally it is an awesome manga to read~ there aren't many other manga/anime like the type of "romance" involved with Bloody Cross. Which i enjoyed the most >w
