Tide-Line Blue - S01

The disaster known as the "Hammer of Eden" wiped out six billion people and left 90% of the world submerged. Fourteen years later, the New United Nations emerged to seek peace in the ravaged lands. Keel, a boy from the town of Yabitsu, lives in one of the few prosperous areas thanks to the nuclear generator left behind by the catastrophe. His cousin, Aoi, serves as the secretary general of the New United Nations. She sees the disaster as a chance to rebuild a world where nations set aside racial and religious differences to support one another-but her vision collapses when nations refuse to change. Meanwhile, Gould, a military officer, believes force is the only way to impose order. With his crew, including Keel’s brother Tean, he commandeers the nuclear submarine Ulysses and launches a coup, declaring war on the New United Nations by attacking Yabitsu.
