Kiyal Bachika

Kiyal Bachika (キヤル・バチカ, Kiyaru Bachika?) is the youngest of the Black Siblings and the most mischievous. Just like Kiyoh, she was helping out in Dai-Gurren's control room until Episode 13, when she starts aiding in the frontlines piloting a customized Gunmen, Kiyalunga (named after herself), which can transform into a shield and lance that are wielded by Kittan's Gunmen, King Kittan.
