| Language of Barsburg|
|Purpose||Facilitates communication between citizens of the Barsburg Empire and the Empire's allies|
The Language of Barsburg is spoken by citizens of the Barsburg Empire. Most of the characters in the series are able to speak it, with the exceptions of Yukinami and Suzunami, who can only speak the language of Raggs. The language of Barsburg appears to be the most widely spoken language in the 07-Ghost world, presumably because the Barsburg Empire is the largest and most powerful empire in the 07-Ghost world and has dealings with many other countries.
