Animes like Death Note and Black Butler?

I hate to say it, but Death Note is the best anime. It's pretty much all downhill from there. You could try watching Code Geass, there's one or two kissing scenes but there isn't much real romance, and it is certainly not central to the plot. An older anime that I really enjoyed was Blood +, but that one has some romance within like the last two episodes of the series. If you want you could just skip the scenes. Anyway, if you liked anime a lot I would check out Code Geass. If not, then it's not worth continuing watching, since like I already said, Death Note is the best one.
