About

Han Rian, the human chosen by the heavens. About five hundred years ago, the heavens opened dimensional gates to Earth, unleashing the Demon King and magical beasts. Simultaneously, they bestowed a system called 'Superpowers' upon humanity to oppose them. To the heavens, this world might have been nothing more than an entertaining game. But there was no choice. As powerless humans who dared not defy the will of the heavens, we had to accept that despair willingly. Those who received superpowers to protect the world were called 'Hunters.' As they cut down the beasts pouring through the torn dimensional gates, they died, yet the cycle of life continued. Families where abilities were inherited emerged, and humanity barely managed to survive. And then, there is the only ability of its kind in this world: 「Regression」. While other abilities settle into a Hunter's soul, 「Regression」 alone was transferred through the hands of its owners whenever it was passed down. Believed to be the final bastion granted by the heavens, that power eventually reached Han Rian across a long span of time. Her parents, who passed the ability to her, lost their lives in an S-Class Gate. The reason she didn't use regression even then was because of her mother's final words. "Use that power only when the world is truly on the brink of destruction. I believe you will make the right choice without being swayed by emotion, Rian." Sixteen-year-old Han Rian suppressed her emotions and saved the power. Just as her mother wished, she didn't use regression even once. Five years later, when Han Rian turned twenty-one, the world ended. An X-Class Gate appeared without warning. The Demon King himself manifested and turned everything to ash. Regression was triggered in the midst of despair. Han Rian returned to the year she turned twenty. However, there was nothing she could change. She was powerless before the Demon King's overwhelming strength, and no matter how many dozens of times she prepared, the result was always a crushing defeat. . . . From the 50th regression onward, she stopped even making plans. She simply waited for the end in a daze. It was only upon reaching the 100th regression that she realized: 「Regression」 was not a key to salvation, but a cruel punishment trapping her in endless despair. However, this regression was different. Within the trajectory of despair that repeated identically every time, she felt a thick aura she had never sensed before. A being wearing the mask of an ordinary human, but who could never be ordinary. In the cycle racing toward a fixed conclusion, an unpredictable crack finally appeared. A crack named 'you.'
