The Spirit King!.After Lucy discovers that Loke is a Celestial Spirit, he reveals the reason why he is trapped on Earth. His owner, Karen, was a super-famous Celestial Wizard. Even though having a famous title, Karen often treats her spirits cruelly. She used Aries to impress other people and uses her as a shield in battle. Loke saw this and appeared in the human world in order to teach Karen a lesson. As long as he is in the human world, Karen will be unable to summon any other spirit nor forcibly close Loke's gate. For three months Loke stayed in the human world. Hoping that Karen will someday realize that Celestial spirits are not tools, he stayed until he grew used to the human world. Thus being able to stay longer. One day, Master Bob, Master of the Blue Pegasus, informed Loke that Karen took a job without his permission and tried to summon two spirits at once, but she failed to do so and died in the job. As Loke's ability to stay in the human world is about to reach its end, Lucy challenges the law that Loke has broken, invoking the Celestial Spirit King to appear before them.
