This is an extremely difficult matter, and a significant change has already occurred over time. Many people have started to believe that without a method for transmitting messages, it would easily lead to a plethora of problems. However, this issue has never been fully resolved. Finding a new type of script could perfectly guarantee a solution to this problem, but developing such a script from scratch now and popularizing it would not be a simple feat.
Thus, using the Demon Race's script is actually a very suitable method to address this issue. Mainly, if there is someone who needs to leave and can interpret it next to His Majesty, then everything would be much easier. However, the same problem arises that it can only work under the premise of absolute trust in the Demon Race. Because to address these issues, one must ensure that the Demon Race's circle is completely trustworthy.
