For reading this manga, it's essential that you have played the 3DS Game itself, 'Bravely Default'.

The story contained in the manga does not differ much from the story in the game, however with a few little twists it does emphasise some of the not-so-major events and does so in a very effective manner.

The art is gorgeous and has really captured each and every character's personalities. The lives of the main cast, Tiz, Agnes, Edea, Ringabel and Airy is explored as they travel through Luxendarc in attempt to awaken the four crystals- just like the game.
As for how fast the plot is moving, it's moving at a steady pace and gives just enough attention to each scene that is recalled in the game.

So far it's great and I'm sure it'll continue to impress even more!
