STORY
After the decline of the once robust fields of science and
technology,
a new energy source known as magic fuels the modern era.
Humanity creates forbidden biological weapons: Gears.
Those Gears eventually stand against humanity in a rebellion.
Although they manage to overcome in the struggle for survival known
as the Crusades,
humanity’s losses are so great that even after several decades pass,
their emotional wounds remain unable to fully heal.
Sin Kiske, the child of a human and a Gear, heads to his father Ky
and mother Dizzy’s wedding ceremony.
Their wedding breaks the ultimate taboo: a union between a human and
a Gear.
Even with the world at peace, it took many years for such a ceremony
to come to fruition.
Despite the complex array of emotions surrounding it, the wedding
ceremony is met with blessings.
When suddenly, a mysterious girl appears…
The fated child inheriting Gear blood–and the mysterious girl who
despises Gears.
Their meeting would shake the world.
