Jinkou Japanese is a dialect and deviation from the "regular" language called Japanese which is spoken by both Ventus and Humans. Jinkou Japanese is very similar to traditional Japanese, but also have some differences. The most obvious thing is that many words in the Jinkou dialect can not be found in the traditional dialects, and vice versa, and the Jinkou have their own alphabet and grammatical structure, which bears no major similarities with the traditional one. This is due to the separation of the Jinkou from other Japanese speaking peoples, and the difference is surprisingly small considering the time it has had to change. It is not as similar to the Human dialect as the Ventus one is, but the Ventus dialect is its own mystery altogether.
