Mizuko Vermillion. She's just another Fairy Tail Mage. If we're ignoring the fact that she's the only living descendant of Mavis Vermillion, the first guild-master. Oh, and she's the water dragon slayer. But nobody knew about that until recently. All her secrets are out in the open, she has nothing to hide anymore. It should feel refreshing. But it's not. When Mizuko is selected to participate in the Grand Magic Games, it's a chance for her to bring her families guild back to its former glory. What she wasn't expecting was to see a familiar face from her dark past pop up infront of her. Her guildmates are about to realise there is still a lot Mizuko is keeping from them. And when they find the truth about her, nobody will ever look at her the same way again.
