Rana is not supposed to XSY with other VOCALOIDs as her company (We've Inc) doesn't allow it. Internet Co. did help We've Inc develop her voicebank, but that's about it. They don't own her character rights and therefore, is not allowed to do anything like adding her into the Internet Co. XSY group since she's not theirs.

Trying to XSY VOCALOIDs outside of their groups (Internet Co or AHS groups) or character (Yukari Jun, Onn, and Lin for instance) breaks the end user license agreement (modification of the files, voicebanks, etc). This is why people don't show XSY loopholes publicly. But aside from that, what made STELLA worse was the intention of obtaining funds from her album using the voicebanks in this way.
