Three students are living fairly normal lives when, one day, they are overcome with intense stomach pain and a star symbol appears like a tattoo on their skin. With the symbol came supernatural powers, as well as enemies coming to kill them.<br /><br />As more and more people develop similar supernatural powers, the story starts to turn into a Battle Royalesque bloody playground, only with an entire city as the setting and many innocents caught in the crossfire.<br /><br />Among other themes, the story asks the question, "When is it alright to kill?" and delves deep into the darkness of the human psyche.
