A Finale for This Wonderful World

At fifteen, Bai Yi became a "Calamity."

After the "Secret Realm" dungeons appeared, his younger sister, Bai Yue, contracted a new incurable viral disease.

To pay her astronomical medical bills, his father was killed in a high-risk secret realm and never came home.

That night, when his mother learned what had happened, she jumped from the roof of their apartment building. As she fell, her blood splashed across Bai Yi's face just as he rushed home.

Bai Yi, who had failed to awaken an ability for so long, finally erupted. A massive "Thunderstorm" swept across several nearby residential districts, leaving countless dead and injured.

Four years later, thanks to a few twists of fate, Bai Yi finally began venturing into secret realms. From then on, the people who had died all those years ago began appearing before him again, one by one.

At the same time, more and more people were dying because of her, with no way to save them.

"When you realize that everything you've experienced seems to have been a script, with every scene set up in advance, would you still want to return to the world you once knew?"

"Of course. I would bring that beautiful world to an end."
