Right now we have English, Japanese, French, German, and Spanish, since they are the most common. You might have not seen someone of them because when the VA database went up we concentrated on getting English and Japanese up first. Truthfully, we haven't even finished adding those. Some shows have some other VAs added, but not many.
Adding VAs takes a ton of time and is very tedious, plus the moderators are busy focusing on adding characters.
You can go here
and request a show to have its VAs added to. But for now we can only add the above languages (assuming the info is available to add them).
