A year after Ran's death, Rei was brought by the downpour to the sea north of the tree where he hanged. There, she let the waves take her life. Nonetheless, what welcomed her when she opened her eyes were the hospital walls and his ghost with a pretty odd question: "Would you still follow me even through the storm?"

In the world of the cursed, everyone has darkness lurking inside themselves. As for her, it turned into a raging void. Enigma Alinac, a first-year in a school of cursed mages, knows nothing of her curse nor what magic she manifests. Nonetheless, upon encountering Emally Yekaterina, she tried to consider it again, which that girl tried to avoid. Witnessing oddities around her, she realized that there still seems to be more to her than she already knew. Emally seems to be a part of it. And that was the beginning of a misfortune as the void awakens.
