Akiko seemed to find something in Raizen's speech funny, she laughed. "Oh please, you said nothing invasive, I wasn't planning to vivisect you or anything. Might just take a few samples, but nothing horrible, and I promise I won't do it while you can't consent. I'm mostly a 'moral' scientist~" the Twelfth Division Captain mentioned. Moving right along, Raizen answered her question about the gender of his Zanpakuto spirit and went on to question if it was something strange. "Hm, a bit yes. Asauchi are special because they can become anything. They are said to become a direct reflection of the soul of their wielder, as such they tend to share major characteristics with their wielders, including major personality flaws and gender. All research indicates that there is a very narrow chance of one having a Zanpakuto spirit that doesn't share your gender. That isn't to say it doesn't happen from time to time, it's just exceedingly rare, like once or twice a generation, so far as we can tell. Of course, it could be higher than that, and the people just died before they could know, or before we could ask~" the Captain noted as she calibrated several nearby machines and too standard readings of reiatsu output and the like.
Raizen seemed to be smart enough to asertain the sort of suggestion that the Captain of the Twelfth intended to make about his present situation. "Hmm, yes. Jinzen. Since you are, at the very least, already familiar with your zanpakuto spirit, asking directly will be the easiest way to find out anything. While you do that, I'll be monitoring your Reiatsu and scanning your body to get a better idea of the composition of your soul," the woman explained of the sort of procedure she was going to use. "I'm mostly going to be trying to figure out if your soul will retain stability. According to all known research trying to combine a Hollow and Shinigami in any way, ends in Soul Suicide. If you happen to be both right now, it could be something of a breakthrough, and I'm interested in it."
