36 years ago, Year 2020...
The world had just started changing. Many weird structures started coming out of the ground.
All the humans were confused about these structures. They tried to explore these places; however, none came out alive from them.
It was after a long time that a person finally came out alive, but even he was heavily injured. He informed everyone that there were many monsters inside these Dungeons that were never seen before.
The new discovery shocked the humans as they knew the risks if these monsters could come out. They started researching these Dungeons.
At the same time, another change was happening in the world.
An eighteen-year-old girl was coming back from college when she felt her body burn. She lost consciousness.
The people who knew her brought her to her home.
