It was supposed to be about a team of secret demon hunting nuns in the Catholic Church. One of them has an angel’s halo in her back that gives her supernatural powers. Turns out that’s part of it but not really the main focus.
Basically the main character is dead at the start. The lead nun of the team with the halo gets killed and through circumstances the halo is hidden in the back of the main character and it brings her back to life. This whole series is mostly her second shot at life and her figuring herself out. Her original life was very bad.
The show is best when it’s focused on the team of battle Nuns and is pretty rough when it’s about her finding herself away from any of the team members.
It’s like a B- series. Maybe C+. It’s not bad but not great. It did entertain me and I don’t regret watching it nor did I ever feel like dropping it.
