Blue Dimension (青き次元 Burū Dimenshon) is a dimension that is accessed by an Azure Dragon Slayer.
Description[]
A realm that appears to be an endless murky blue-colored void. The time within this world appears to be out of sync, as one second in this dimension is about an hour's worth of experience upon leaving it, therefore any damage sustained in the Blue Dimension is increased in exponentially after exiting it.[1]
Anyone brought into this dimension floats in the air of this endless space with no mobility, making it difficult to dodge oncoming attacks[2] unless they also possess some form of Spatial Magic, allowing them to coordinate their movements.[3]
Within this world, the user has complete control of the space within it, not only bringing targets into it to deal excruciating damage, but also manipulate the space itself to form spatial constructs such as various sized blades and summon chains from any direction to attack and ensnare their target, essentially their imagination becomes their power.[4]
The color of this world can apparently change when a Mage’s magic power overwrites the user’s own Magic, eroding it into the same color as their aura. This may cause the user to lose control of the space within the dimension.[5]
