Potential applicant here (considering Crona from Soul Eater) with two questions.

1. What is the policy on two characters that share a body? In Crona and Ragnarok's case, it's more "magically conjoined twins" than possession.

2. What is the policy on characters who have not (and most likely will not) have their sex revealed in their canon? Crona is essentially genderless mentally, and I would prefer not to have to pick a sex.
