Prologue
At the beach…
A red haired six year old girl with a twin tail was running on the beach. She wore a white sundress with a red ribbon choker and her twin tail was held by a blue and black ribbon. Behind her there's two young boys by the same age, one with a dark blue hair and one with a bright blue hair.
"Gray, Jellal, hurry over here!" Shouted the girl.
"we're coming! Geez Erza, you don't have to run that fast." Said the dark blue haired boy.
"but I want to see the sunset…" Erza replied. "… for the last time at least, with you guys…" her face shows sadness.
"…" Jellal remains silent.
They arrived at the cliff.
"wow, it's so pretty." Said Erza. "I wish we could stay like this forever." She said with a sad tone.
"I don't want to go to America, I don't want to be separated with you guys." Her tears began to fall down.
"don't worry Erza" said Jellal.
Erza looked up to see him.
"we're always be friends no matter where we are." He gave her his big smile.
"yeah, and besides we can still keep in touch, right." Gray added. He also gave her a big smile.
Erza stunned by their words. But she also felt the warmth of her friends.
"right!" she said with a smile.
"hey, let's make a promise."
"a promise?" asked Gray.
"yep, a promise. A promise that we will meet again someday." Said Erza.
"but we need something that will symbolize our promise."
She looked around and found 3 matching seashells. "ah, those are perfect!"
She picked up those shells and then she took off her ribbons and tied them around the shells. She tied the last one with her choker, then she gave them to her friends.
"those are…"
"these shells are symbol to our promise." She tied them to their wrist.
"promise me that we will meet again someday"
"we promise!" They hugged each other.
The next day, Erza was taking off to America. The boys saw her flying away.
'I promise we meet again Erza' thought Jellal.
