Language
Grinsha and the other Over Lords seemingly has its own language. This is similar to the Gurongi Language from Kamen Rider Kuuga, the Undead from Blade and Fangire from Kiva, in which an enemy faction has its own language that the Japanese do not understand. As with the Gurongi, Japanese subtitles aren't provided for Grinsha's speech, it is unknown if they will be provided in a later release such as a TV rerun or DVD release.
