Now, here are some headcanons for the demonic nun and runaway criminal, Sarvente and Ruv.
1. Sarvente's church is magical and she can place it anywhere she wants.
2. Ruv doesn't like it when people make jokes about Russians, because he finds them very offensive.
3. Sarvente and Ruv's full names are Sister Sarvente and Zavodila Ruvyzvat.
4. When Sarvente first met Ruv, she thought his real name, Ruvyzvat, was a little difficult to pronounce, so she shortened it to Ruv, and it stuck. In turn, Ruv decided to shorten Sarvente's name to "Sarv".
5. Sarvente doesn't usually allow Ruv to sing in her church, because she knows that his singing voice isn't as elegant as hers. Whenever Ruv sings, she has to make sure that she has earplugs ready.
6. Ruv is aware that his singing voice is loud and booming enough to cause an earthquake, so if he does sing in Sarvente's church, he has to make sure his microphone isn't plugged in first. He still manages to shake the church anyway.
7. Both Sarvente and Ruv love ice cream. Sarvente's favorite flavor is Neapolitan while Ruv prefers cookies and cream.
8. Ruv is not intimidated easily, unless it's seeing Sarvente in her demon form.
9. Ruv wants to marry Sarvente, but is a little too hesitant to tell her. He plans to wait until after he and Sarvente have had a few dates to ask her hand in marriage.
10. Ruv is bitter rivals with Whitty.
11. During almost every situation, Ruv keeps the same deadpan expression he always has.
