This is how I roll; I deal in IC being IC, and OOC being OOC. I've already spoken to Osaka about the Lazarus portion, and Luca on the Akahar portion, the two have been meshed up and things are pretty kosher. Play Ny'za as Ny'za is meant to be played, this is about the role, not some meta appeasement fest.
As for rank, yeah, that's my bad, we've yet to hammer out the Fyunnen caste military command tree, in relation to the LSDF command tree. As it stands however, Ha'reiel carries the authority of the Matriarchy in the form of theological-political doctrine, as opposed to LSDF rank-and-file which is structured in a way which is divorced from the theocracy of the core Matriarchy. However, in terms of real-world equivalents, as a Chief Chaplain, Ha'reiel would carry a rank kin to a Major General. As that stacks up to Keib's Sub-LT turned Commander rank, its pretty heavy.
I'll speak to Luca further on the matter however.
