Considering that the result of Reincarnation could be considered similar to the result of the Swap Technique, and that Maria was one of the few people capable of such, it could be that her ability to use the technique coupled with her ability to hear Levia and Behemo (shared only by Kiril) allow her to reincarnate. She is the only known human with this combination of abilities. I don't think it's particularly likely, but it is possible.
