Kellen Woods grew up never knowing a normal world. By the time he could walk, his mother and father had already sealed several serious gates that threatened the safety of his hometown. By the time his sister was born, they were famous worldwide.So the world held their breath for when Kellen and his sister came of age, waiting to see what kind of power they would awaken.His sister was just like his mom, same power, same class, while Kellen, woke up one day to find out what it meant to be special in a family the world watched. But in the worst way.Awakening weaker then your powerful parents wasn’t unheard of, but when your younger sister awakened at the same class as your parent, anyone would feel inferior. And Kellen, never one to ask for hand outs, left the comfort and safety of his hometown to become better than the weak brat everyone thought he was.Kellen went to the front lines, to where the gates normally broke out. From there, Kellen worked hard, and then worked some more until no one could doubt that he was good at his job. He got so good that even with his lower class, people would still hire him to help. But Kellen never took it to heart. He had learned a valuable lesson on the front lines. Classification only meant shit if you walked back out of the gate. Otherwise, shut your mouth and listen to those with more experience. They determined who made it out alive or not.But Kellen was tired now. He had gotten everything out of his system, and the fast paced life on the front lines didn’t suit him anymore. Now, he wanted to go home, buy a house, maybe find a nice man to settle down with, and live a normal life.All the while, the yellow eyes he’d met on the front lines haunted him, no matter how much he tried to forget about them.Especially since the Esper they were attached to refused to let him go.

And in the present day, large numbers of the population have crests, and those that don't are treated as second-rate.This was the case with Marcus, who spent most of his life doing odd jobs—until one of those jobs led to his demise.At the hands of whom??The son of a major crest-bearing house.Marcus is reincarnated into the body of his killer and soon finds that despite being from a major house, the boy did not have a crest.At least, not one that was bestowed upon him by God.
