At The Altar(sketch) (Patreon)

While doing this sketch I got the crazy idea for a series in which battle nuns have to pass a certain initiation to be able to battle the servants of Hell. They get chained to a special altar while their sisters summon  a lesser demon. If the appointed nun survives the ordeal, she gets promoted to a battle rank. This one time the sister screw up the summoning and a Greater demon comes forth ...

It's been a while since I did nun themed series anyway.
