Crystal Keys (being rewritten)
If things were different, Fairy Tail, would have said a proper goodbye to the girls. If things were different, Lucy, Levy, Erza, Wendy, and Juvia wouldn't have gone on that quest. But you can't change the past. Lucy, Levy, Erza, and Juvia have been missing for a year after going on a quest, only Wendy came back. The four are greatly missed especially by Natsu, Gajeel, Jellal, and Gray. But one day Freed and Laxus discover something that will change everything. Crystal Keys trap humans into celestial keys, and there are four celestial spirits that look like the missing four standing at the doorway of Fairy Tail. But this time it's up to someone you wouldn't expect to save them.
