The homeworld of the male humans after the gender separation by Gran Pa and Gran Ma. This planet is ruled by Emperor Zen, commonly referred to as Lord Gran Pa, who then revealed to be Hibiki Tokai's father.

Unlike Mejeiru, which has abundant resources which they waste frivelously Taraaku is a desolate world that has precious few to begin with. This lack of much has forced the men to become highly resourceful, learning to do anything with as little as possible and taking offence to un-needed waste.

Most food on Taraaku consists of food pills. Children from Taraaku are grown in machines using a combination of 2 mens genes.

Due to the lack of resources the men are also less technologically advanced than the women, preferring more powerful weapons to other forms of technology. The society is highly militaristic with no holidays to celebrate except military parades. The holiday of Christmas having been long forgotten by them.
