Iris was born in World DE-1, a world that mirrors Earth in the 2000s. With her birth, a series of tragic loops was set in motion, which were gradually unraveled by the efforts of Arata Mizunashi and his team. With her goodwill restored, Iris created a copy of World DE-1 named World DE-1.5. Here, feuds gave way to friendship, each person a perfect cog in a perfect world. But a new crisis now threatens the peace. A mysterious man has entered the fray, and he leads a group of people who look identical to the world's former heroes. Our new hero, Sayaka Hiwatari, confronts the rising chaos, where friends and foes seem impossible to distinguish.
