50 years ago, the Earth broke into a huge world war, destroying most of humanity. The remaining settled in Australia, which soon became Makiani Severity. Humanity soon learned how to manage magic and witchcraft, teaching the kids early. Every year, on June 16th when the kids were 10, they'd have The Droppers. An event where kids would enter adolescence by killing others. The Droppers allowed 8 victors out of 16. When the kids turned 16, they'd enter a second event, The Aftermaths. The Aftermaths allowed 4 victors out of 8. Those victors of year 2070 include kids Takeo Daisuke, Kamei Toshijimi, Daxia Kaede and Isamu Katashi. The four all hated The Severity, soon forming the small group, Ansevere. Each day they become closer to bringing down The Severity, although facing a new problem from the year older twins, Saki and Seki Madoka, who know of their plans to take down Severity. Will the four come close and take down Severity? Or will they be stopped by the Madoka twins and executed?
