Without approval from Lunise, Meesei did not want to share any more about her situation than was needed for Pircalmo to help her. She was not sure if Lunise wanted her father to know about the work they were doing to fight against Vile, but at the very least, Meesei was sure that Pircalmo would be accustomed to the restrictions and secrecy that came with being a Justiciar. There could be dire consequences for sharing restricted information, and she doubted that Pircalmo would want his daughter taking that risk. With Meesei at the very least being associated with Lunise, that risk could also reasonably extend to her in Pircalmo's mind. 

"As you said, the Hist certainly has a destiny in mind for me. One of importance to them that requires me to be capable." Meesei answered vaguely before shifting back to the subject at hand. "Lunise did inform me that you do not have as extensive of expertise in matters of souls, but I still have a suspicion that your knowledge of the physical body may be helpful. My soul is clearly kept stable in this body, and I find myself curious on what exact properties of a physical body, or even my specific body, would keep a soul together. Perhaps there is a chance that I might use that knowledge to protect me beyond death? In truth, I am not sure that it is likely, but I am sure that you can understand why I would want to explore all of my options."
