Dayakka Littner is the former leader of Littner Village, abandoning his post, when most of Littner joined Team Dai-Gurren. His Gunmen is the Dayakkaiser, but after the seizure of Dai-Gunzan, he acted as the captain of Dai-Gurren during battles, while Kiyoh piloted the Dayakkaiser in his stead. After the timeskip, we discover that Dayakka is appointed the Minister of Food Affairs for Kamina City, and he and Kiyoh have married and expecting a child. With the threat of the Anti-Spirals, Dayakka resigns his post and returns to his duties in Team Dai-Gurren. (Source: Wikipedia)
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.
Age: 16; 23 (second half)Height: 160 cm Weight: 46 kg Yoko is a girl from Jeeha's neighboring village Littner, who had been chasing the Gunmen which entered Jeeha village. She wields an extensive range of firearms which include a long range sniper rifle (which she uses most frequently) modeled after the Barrett M82 and hand guns (which can be assumed is used for mid-range or close combat) and has previous experience fighting Gunmen. Although she is of the same age group as Simon, she is mature and one of the more rational members of the group. Despite always badmouthing Kamina for his reckless behavior, it did not take long for her to confess her feelings to him, which he returns. She was also Simon's love interest, until Simon discovered that she was in love with Kamina. He seems to have given up on her since meeting Nia. In episode 13 she proceeds to tell Simon that she was in love with Kamina in which Simon replied that he already knew. After the war, Yoko decided to not take part in the administration of Kamina City and decided to become a school teacher for the first new children born on the surface, but not before asking Simon to take care of Nia. After the war with the Anti-Spiral, Yoko became principal of the school she once taught at. (Source: Wikipedia)

Sei's older sister whom Sei greatly respects. Kotaro commented that both Sei and her do not like to talk much. The Princess has lived for a very long time and is also a descendant of the chaotic bloodline. She resides in the Sacred Precinct with Crow, where Jiro and Kotaro previously stayed at. She was sad to see him go, so Kotaro consoled her by saying he will write to her when he reaches the Special Zone. Despite her quiet demeanor, she apparently has a short temper and while she enjoys Kotaro's company, if Kotaro does something that angers her, the Dark Princess does not hesitate to hurt him. Her powers are great enough to warp and change the very weather surrounding her. -wikipedia
