From Fairy Tail. Cosplayer is Kelsey.
"If you ever drop my key again... I will kill you." "The Water Bearer" (宝瓶宮 Hōheikyū), is a Celestial Spirit that is one of the 12 Golden Zodiac Keys. She is Scorpio's girlfriend. Her key was owned by Lucy Heartfilia until she sacrificed it in order to summon the Celestial Spirit King. Nevertheless, Lucy still owns a part of her key but, since it's broken, she can't be summoned ever again.
