To celebrate its 40th anniversary, Japanese animation studio Shaft, Inc. is creating an art exhibition called "Madogatari" that combines two of their most popular anime properties: Puella Magi Madoka Magica and the Monogatari series. The event will run in Tokyo November 27 to December 2, 2015, followed by stops at Osaka December 22-27,, then Sapporo February 9-14th. The bombshell out of the opening was a "Madoka concept movie."
