Blue Flame Art: Four-Point Hell Barrier

The user gets within the proper range of the target and then presses the proper Fuinjutsu formula to the ground. As the formula unfurls and lengthens, four pillars of blue flames emerge, and then from the four points the 'walls' of the barrier spread out, as do the 'ceiling' and 'floor', resulting in a cube-shaped cage made of blue flames. Written into the formula for this barrier is the user's Flying Thunder God seal. Due to this, the user is able to simply teleport at will within the confines of the barrier, even teleport out of it.
