Emmy Scarlet is Erza Scarlet's younger sister. The two of them went through everything at the tower of heaven together, and then went to Fairy Tail together. The two of them felt at home at the guild. Emmy got along with everyone at Fairy Tail. But only a mere two years after joining, she was kidnapped by a dark guild for unknown reasons. After searching for a year, everyone at Fairy Tail believed that Emmy had been killed. But after a year in captivity, she managed to escape.

Emmy went in search of Fairy Tail, travelling from place to place, until she meets Lucy Heartfilia. The two girls form a bond, and Lucy doesn't want Emmy to leave. So Lucy convinces her Father to take Emmy in as his own daughter. Emmy reluctantly agrees to stay with Lucy.

After many years at the Heartfilia estate, Lucy and Emmy have formed a strong sisterly bond, and they run away from the mansion in search of Fairy Tail. The two travel from town to town, until they meet the fire dragon slayer in the town of Hargeon. He takes them back to Fairy Tail, and the members are all happy to see Emmy again, some members happier than others. But what Emmy didn't know was that a certain pink haired dragon slayer and a ice mage with a habit of stripping, both had strong feelings for her and were two of the happiest members when she returned. But the happiest member of all was Erza. Erza couldn't believe that she had her younger sister back.
