It's about these demon like entities that are basically feeding on peoples' souls. And some dudes beat em' up.

But the story is called Trust because the entities come in 2 different forms.

Mimickers : These are entities that sneak up on people, feed on their soul (which kills the person), hides the body and then transforms into the person they killed.

Possessors : These entities are able to possess people. That's kind of it. They go find people to kill, unless the host (and entity) are killed.

All entities are pretty damn strong, and are tough to kill. Using baseball bats, pipes, axes, hell - even a fucking log are pretty good going against these goons.

The worst thing is that the entity could be anybody.

That's kinda the idea.
