The Secret of the Nuns (Patreon)

The big secret, I shall add. ( ͡° ͜ʖ ͡°)

Now, slightly off-topic: recently finished the movie Love Exposure and realized how sapphic plotlines intersect with catholic themes often in japanese media (Fatal Frame is another one, but I believe you can find even more examples if you look hard enough - either on anime or movies).

That's just a small piece of trivia to spice up your day.
