Karen Lilica

Karin was a mage who belong to the Blue Pegasus Guild, as well as being a famed Stellar Spirit mage in the Fairy Tail world. However she was very conceited to her Stellar Spirits, thinking them more as tools and slaves then living beings. Her guild master, Bob, warned her that she would suffer should she continue abusing her spirits. But these warnings fell on deaf ears as Karin believe one of her spirits, Aries, had told on her. Just as she was about to punish the timid spirit by forcing her to remain in the main world for seven days (which would have killed her as no Stellar Spirit can remain away from the Spirit world that long) Leo suddenly took her place. Demanding she terminate the contracts she had with both spirits due to her abuse and that no other spirit was willing to work with her. Karin however refused and tried to close his gate but Leo was much more strong willed then she thought. And since he was out she couldn't summon any other spirits as well.

Leo waited at some nearby ruins to see if Karin would give into his demands. The first time was after ten day, Karin tried to talk the weaken Leo into returning but he stubbornly refused as did she to his demands. 30 days afterward, Karin was now pleading with him but he saw through her lies prompting her to stomp on him and proclaim that once he was gone she would be free to summon Aries and treat her ten times worse. However this wouldn't be the case as three months passed and Leo still remained in the human world. During that time Karin went out on a mission and died as a result due to her lack of stellar spirits.
