Chaos_Gray

Neil Zoltan, the world’s first legendary assassin, is ambushed and killed, only to wake up in the body of a young student in a world far different from his own. 

Neil discovers a mystery called the "Observer" that grants him strange powers. 

As he unravels the mystery behind his reincarnation, Neil must regain his strength, uncover hidden enemies, and seek revenge on those responsible for his demise. 

However, the rules of this new world are different—and so is he.

His death was just the beginning.
