Black★Rock Shooter (TV Anime)
Although Chariot used Mary, her legged vehicle, as her main weapon to fight Black★Rock Shooter at first, she resorted to wielding a sword and a shield to continue fighting after Mary got destroyed.

The shield largely resembles one of Mary's wheels, but it is smaller in size to fit her use. In addition to its defensive nature, the shield can also protrude spikes to pierce opponents.
