帝都物語
Other apocalyptic standards like earthquakes are employed, but the apocalypse of Clamp's manga trades the religious element for an environmental theme. Inspired by the Gaia theory that the Earth itself is one living organism, Ohkawa crafts an endtime brought on by humanity's abuse of the planet. The constant earthquakes the Dragons of Earth cause resulted in a negative backlash from readers and editors because of similar incidents in real life. The story reflects environmental concerns in its depiction of Judgment Day. Mankind exists in binary opposition to the Earth. By the end of days, humanity has become such a nuisance that the only way to save the planet is to destroy the whole of civilization. With mankind gone, the planet can regulate itself back to health and experience a rebirth. The Seals, however, look to preserve the status quo and to entrust the future of the planet to the people. "Teito Monogatari", an award-winning historical fantasy novel, inspired aspects of "X's" mythology.
