Bounded as the Devil

Illumga, was born in the slums of Saturina Empire, one of the greatest and influential capital in their world. Inside the Empire, he was known as the bloodthirsty demon, taking innocent lives and giving them sufferings. For him, seeing blood is a normal day routine. No matter how old or young the person is, he does not choose as long as he keeps devouring their fears. One day, upon having an assassin's job on killing a certain woman whom he got bored to, his life began to change. Unexpected thoughts come running in his mind.  'Why can I not sense fear in her?' is what he always thought.
