hmm morten and nroejb allready mentioned much.
i'd like to add
Sanctuary and Strain.
Its nothing supernatural, but it has lots of fights, deaths and SEX
also since you like Tenjou Tenge (what i dont. i just wanted to say this^^)
you should read Change123. its in many ways quite similar to tenjou tenge. yet not that senseless
i dont want to say change123 has a deep story or something like that. its quite senseless too. but not as much as tenou tenge. and its not boring
