Najya, a 19 year-old girl finds herself somewhere unknown. Except for her own personal information, she remembers nothing else. Suddenly, something like a sphere ball called out to her and stated about a "Challenge". If she can finish as much challenges set by the system, eventually she will get her questions answered such as why she was there, how she got there and so on. As Najya accepts the challenge, she kept on teleporting to cities to defeat wierd creatures.

Despite going to numerous locations, she still hasn't found another human like her. Just monsters. And she thought she'd be forever alone in this monster-infested world.

One day, as Najya was clearing up another challenge, after a whole load of uncountable challenges, She was injured badly and was at the brink of death. She saw a figure, somewhat almost like her's coming towards her. Her vision was blurry but she was certain that it was a human being like her. What will happen to najya? Will she still be alive? Will she finally find a human like her? or will she die, leaving unanswered questions behind?
