The Laufeyson Bloodline System

Loki was an ordinary boy with abusive parents in prison. What happens when he becomes something stronger? He is forced to go to military school for 2 years. He learns new powers, makes friends, and discovers a sinister plot. Now, it's up to him, his friends, and (unexpected) allies to come together and stop the evil plan that could wipe out half the humanity. (Note: this story doesn't focus on the system that Loki has that much, it focuses more on the plot.)
