Death of Karen Lilica

Death of Karen Lilica is an event that took place at the year X781.

Prologue
Karen Lilica is a Blue Pegasus Celestial Spirit Mage widely known for her beauty and her multiple Sorcerer Magazine covers. Due to her widespread fame, Karen usually brings a group of men with her whenever returning to her guild. On one such occasion, Karen summons her spirit, Aries, to entertain the men while she does something else. Seeing her actions, Master Bob scolds her for it, telling her that Celestial Spirits are living beings with feelings and warning her that she will suffer as well if she continues to do as she please.

Because of her being scolded, Karen later turns her anger on Aries, beating her up and threatening to make her remain in the human world for a week. She then prepares to chain her up but Aries is suddenly replaced by Karen's other spirit, Leo. Leo tells Karen to release him and Aries from her contract, telling her that she had lost her right to be their summoner and that other spirits are afraid that she might get their keys. Karen, however, refuses and tries to force close his gate. However, Leo refuses to return and says that he will remain in the human world until she releases them, making it impossible for Karen to summon other spirits due to the limitation of her Magical Power. Leo then leaves, telling her to visit him when she comes to her senses.

After about ten days, Karen visits Leo in the ruins near the town, asking him if he has yet to reach his limit. Leo, however, refuses to return unless she frees him and Aries. After a month, Karen returns to him, begging him to return and promising to never mistreat Aries again. Leo, however, stands firm with his decision and gets beaten up by an enraged Karen.

Death
Despite knowing that she will be unable to summon other Celestial Spirits because of Leo's rebellion, Karen decides to take a mission out of desperation. During the mission, however, she is killed by Angel of the Oración Seis who takes Aries's key.

Aftermath
Due to indirectly causing Karen's death, Leo is forced by the Celestial Spirit King to remain in the human world. While there, Leo takes the name of Loke and becomes a member of Fairy Tail. He later begins to date multiple girls as once, mimicking Karen's lifestyle, whilst carrying the guilt of her death. After three years, Loke begins to weaken and is about to die. However, he is pardoned by the Celestial Spirit King and, with Lucy's help, is allowed to return to the Celestial Spirit World as her spirit.
