The world is in ruins and is hell itself due to man's envy for power. The blue sky is now gray and the sun is farther away then ever giving little heat and light. Humans are now considered animals and have all seperated from eachother creating ruthless tribes that kill eachother viciously. God has only iven 3 sources of power to a special three that are marked with their special powers. 

Jiyeon-(18) She grew up with Eunjung, and Hyomin by her side. Together they made not a gang but a sisterly bond. She is soon seperated from Eunjung and Hyomin and given a power. She struggles at first until she finally learns to control it and creates her own gang called the Night Wolf. Jiyeon finds herself falling for Kai and Baekhyun 2 boys who are from a gang. Jiyeon starts off as loving and all the good stuff but turns evil and the end is unknown for her. 

Hyomin-(20) She grew up with Eunjung and Jiyeon. She teaches Jiyeon to fight for self defense and then a gang attacks them when she was only 14. Jiyeon 13 and Eunjung 15. The last thing she sees is Eunjung being knocked out on the floor Jiyeon being beaten up ruthlessy and deserted on her own and herself being stabbed by a knife while Jiyeon watches and thinks shes dead. Hyomin tells herslf Jiyeon and Eunjung is dead and shes on her own. She continues to be a lone wanderer until she is given the mark for power and enters a small group called the Sunrise.

Eunjung-(21) She wakes up lost and alone. She cant find hyomin or Jiyeon and is given the power and stays a wanderer not for long because she disguises herself and joins a gang while searching for Jiyeon and Hyomin with little hope that she has. 

Kai-(20) He is the son of the gang leader who killed or attempted to kill Jiyeon's small sisterly bond group. He takes over the gang and he watched over Jiyeon while she was so hurt at first that she was alone and nearly turned blind. Has no idea that this was his fathers doing. His gang eventually chases him out so he creates a gang called Exo-K. 

Baekhyun-(20) He is in the gang Exo-K and falls in love with Jiyeon when he first met her. She is tough but he soon finds the soft side of Jiyeon when he meets Eunjung and helps her find Jiyeon because he sees Jiyeon is using the power for the wrong reason.
