Kiyal Bachika is the youngest of the Black Siblings and the most mischievous. Kiyal's name comes from yaruki meaning 'willingness'. 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 first half, Kiyal has a fang sticking out on the left side of her mouth. After the time skip, she lives with Dayakka and Kiyoh.

In the distant future, people build their homes and raise domestic animals in subterranean caverns. As a result, they live in fear of the occasional earthquake and cave-in, and have been for hundreds of years. Jeeha is one such village. One day, a boy named Simon happens to find a small, shiny drill whilst digging to expand the village. At the same time, Kamina, a guy who believes that there is another land above the village, persuades a gangster to break through the ceiling in order to leave the cavern. Suddenly, an earthquake occurs and the ceiling collapses, followed by a big robot breaking through the ceiling. Kamina is now sure that there is a world above them. Recklessly, he begins to fight against the robot. At that moment, another person appears from the land above. It is a girl by the name of Yoko. With a rifle in hand, she had been tracking the robot. However, all she could do was distract it. Then, Simon shows what he had found to Kamina and Yoko. It`s a mysterious robot whose head is also its body.
