Anime recs and requests, a new beginning

[Jinx999]

What I really wanted to ask about, though, was one I vaguely remember but never actually watched. I'm pretty sure the setting was not-WWII, and the witch MC rides an a machine cannon like a broomstick, but aside from that I have no real information, save that it would probably have been probably early-noughties or early- to mid-teens, as I was not online with anything capable of watching streams or torrenting from around 2008 to 2012 and it was definitely at least five years back. That doesn't strictly rule out the middle period, or for that matter late 90s, but they don't feel likely. Anyone know what it was?

Could it be "Shuumatsu no Izetta"?
