 If you liked
Trinity Blood

 ...then you might like
Bleach

Both have action, powerful characters, and comedy in it.
In Trinity blood the vaticans are trying to protect the people from the vampires, whereas in Bleach it is the job of the shinigami to protect the people from the hollows.
Also, both Kurosaki Ichigo and Peter Abel Nightroad are very similar in seriousness, power, protecting the people that are important to them and are funny when not fighting.
