In the early 21st century, an island nation suffered an unprecedented disaster: an earthquake, a tsunami, and a nuclear accident struck all at once. At a hospital near the disaster zone, a mixed-race woman gave birth to triplets alone, then abandoned them and mysteriously disappeared. The frailest of the three, the youngest, a boy, was adopted by an orphanage. The eldest and second-born, a pair of girls, were fortunate enough to be adopted by a wealthy businessman. Their different upbringings shaped their distinct personalities. As they grew up, the three children of disaster gradually came to understand their abilities and became troubled by a series of questions. Their arrival gradually brought a series of crises to humanity.
