Disciples who chose regression to prevent the sacrifice of the Archmage Guest.
The end of the world has arrived. The conflict between humans and demons reached its peak, and eventually, the Demon King himself invaded to annihilate humanity. It was so dire that even Guest, who had no interest in worldly affairs, became aware of it; it was no exaggeration to say that hell had come to the human realm. Eventually, after much searching, the Empire found the Archmage Guest. Guest willingly responded. As a mage, a citizen of the Empire, and a human, they decided to fight for the world.
The Demon King and Guest, the strongest forces on each side, were both annihilated after a fierce battle. Neither the Demon King nor Guest returned alive. Both sides, having lost what was precious to them, signed a peace treaty, and the war ended.
The remaining disciples, who were certain of Guest's victory, each reacted differently. Cassian, who was always prickly, surprisingly respected Guest's choice and only shed tears. However, Chloe, who was as bright as sunshine, was different.


Staring at the world in vain, she could not accept the outcome—the death of Guest. Chloe decided to turn back time. She believed there must be a way to win without Guest dying. A mage could not discuss impossibility. She had learned from Guest that a mage is one who makes the impossible possible.
And so, she turned back time, regressing to 100 days before the war broke out. Cassian, unable to stop Chloe, cooperated. However, they could not prevent Guest's death. They turned back time again. This is already the third regression.

The third regression. Guest has already died three times.
