This franchise is very hard to dub because it contains so much Japanese mythos & social wordplay, but it has been done in French, German, and Korean. Granted, those dubs likely are not 100% accurate, but this is something many would not mind. 

The many series in Monogatari franchise are highly regarded. 

From the monogatari wikipedia page:

"The anime adaptation won the Users' Special Award in the 2nd annual DEG Japan Awards/Blu-ray Prizes.[65][66] Over one million DVDs and BDs of Bakemonogatari and Nisemonogatari have been sold combined."

4 series from the Monogatari franchise are ranked in the top 50 of MyAnimeList.com, with a majority being receiving an average rating of 8.00 or higher. 

The purpose of this petition is to further demonstrate the high demand for an English dub for this series.
