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 front-lines piloting a customized Gunmen, Kiyalunga (named after herself), which can transform into a shield and lance that can be wielded by Kittan's Gunmen, King Kittan.
Kiyal's name comes from yaruki meaning 'willingness'.
Kiyal has a fang sticking out on the left side of her mouth.
After the time skip, she lives with Dayakka and Kiyoh, childishly criticizing Rossiu's actions against Simon.
- She was originally voiced by voice actress Kana Aumi in Japanese, and in the English ADV Dub by Kira Vincent-Davis.
- She (arguably) has the smallest role in the series out of the Bachika siblings in the anime. In the manga, her role is significantly increased.
- In the second round of Parallel Works, Kiyal gets her own segment, "Kiyal's Magical Time", featuring a pre-teen Kiyal in her own "Magical Girl" series.
