The Ghost Handler's Notes

Something Like Mysterious Revival, With a Tough Guy Lead. No Fawning Over the Protagonist or Getting Weak-Kneed Around Women

Something like "Mysterious Revival", with a Buddha-like protagonist. They're supernatural entities, not ghosts, and they can only kill according to specific rules. It's fine if they cooperate with the protagonist, but don't make them too obsequious. Also, no characters who lose their heads whenever they see a woman. Thanks, everyone.
