Vampire+Rosary, but its really perverted I don't watch just someone told me.

The series you listed I don't think are that similar to Death Note. The series that comes to mind when I think of Death Note is Code Geass.

Have you seen Darker Than Black yet?

! death note isn't horror seriese....second if u want series "smart like death note than that would be Code Geass"...U want cool horror watch "hellsing","devil may cry"...That would probobly keep u ocupied: )
