Personal Gunmen: Dayakkaiser

Kiyoh Littner (born Kiyoh Bachika) is the oldest of Kittan’s younger sisters, and possesses an extremely large bust. In episode six, when fighting her way out of an enemy Gunmen, she is shown to possess good combat ability. She was helping out in Dai-Gurren's control room until episode 13, when she starts aiding in the frontlines, piloting Dayakka's Dayakkaiser Gunmen, which she begins to use when Dayakka begins to command aboard Dai-Gurren.

After the timeskip, we discover that Kiyoh and Dayakka have married, and Kiyoh gives birth to a daughter, whom she names Anne. Anne happens to be the newborn that makes the human population reach one million, and as soon as she is born, the Human Extermination System begins.

In the manga she, Kittan, and her other sisters appear earlier in the story (during Team Gurren's time in Littner Village) and explains to Simon that their home village, Bachika, was destroyed by Viral.
