That would work quite well, Skylar! Given how Ryuunosuke is at the moment not so recognized by all the powers in the Mitsumine lands and the branch family are pretty much ruling things in the Capital, Tenzin could remain at the capital while sending her as his subordinate to keep and eye and court favor with the young heir to appraise him. Hmmm also, her double entry bookkeeping could be something she's still figuring out and doing early tests on so that she can make the breakthrough and employ it for the first time sometime in the RP.
