Strike Witches
In a postscript column in "Comp Ace", Fumikane Shimada had mentioned his desire to use his Mecha Musume concepts across a variety of media, leading to the production of the "Strike Witches" OVA by Gonzo. However, at about the same time Fumikane was also contracted to create the character designs for "Sky Girls", which had its televised run in late 2007. During this time there was no word on the further development of a "Strike Witches" animated series, although promotional items such as plastic figures of the OVA's characters were released. Not until December 2007 was the anime officially announced, after which details were slowly released, such as the casting of the remaining main characters that had no lines in the OVA.
