The action of Toward the Terra is set in the distant future. Humanity had to migrate to other planets following the environmental degradation of the Earth. The first opening theme, spanning episodes 1-13, was "endscape", performed by the band Uverworld, while the first ending theme is "Love is", performed by Miliyah Kato.
By trying to develop the industry at the expense of nature, humanity has finally managed to make Earth uninhabitable. The few survivors then created a new government called Superior Domination and left their home planet. To avoid past mistakes a strict new system, called "Universal Control", was introduced. Indeed, to achieve the perfect society, births are regulated and every child on the day of his 14 years is subject to a test of maturity. If the test is successful, the child becomes an adult and comes to himself.
