Gatekeepers 21

Some years into the future, a strange, unexplainable natural disaster has broken off a piece of the Japanese mainland. Known as the Lost Ground, it is now inhabited by people with Alters -- machine-like extensions of their own will. In order to keep the peace on the Lost Ground, the HOLY organization uses its own Alter capabilists to police the region. In the midst of the chaos is a young man named Kazuma, whose life will soon change forever as he discovers his hidden abilities, and how to wield them.

Kamui has returned to Tokyo with a traumatizing past, but he is not the only one. Many people are returning to Tokyo for the same reason: they play a part in the End of the World. The Dragons of Earth and the Dragons of Heaven now must fight for the destruction or safety of the world. But is this troubled Kamui really the key to saving the world?

Under Tokyo there is a city where select people have a natural ability to control the elements. But when an uprising takes place, Chelsea Rorec helps Ruri, a mysterious girl known as the maiden of life, escape from this secret world. Together, they stumble upon Asagi Rumina, a man who becomes determined to protect Ruri from those who pursue her; though unaware of the power he's up against, the task will prove difficult to say the least. Now, with his newfound powers to control the wind, Rumina must save Ruri, theu nderground and the surface world from ultimate doom.
