High school student by day, serial killer by night
Vexa behaves as a normal sixteen-year-old student during the day. However, she has another identity unknown to everyone. At night, she discreetly terminates her fellow students such as the bullies, rapists, drug addicts, killers, and many others having bad records.
As the authorities found dead bodies dumped in Tuson's River, the school administration decided to cooperate in finding the suspect. As the investigation continues, Vexa's hidden identity becomes threatened more than ever.
