Blood Release: Dome

At the wave of a hand, the blood surrounding the user and his opponent, assuming they're both positioned in the blood-populated environment, with a dome of ever-encompassing blood. The fluids will continue to rotate with a high velocity in order to create a pressurized barrier, preventing all forms of physical escape by simply ramming into its structure, and should that even be attempted, the culprit will be sucked into the dome's body, and not only crushed by the pressure within, but also reduced and converted into blood to strengthen the barrier-like dome.

That isn't to say though, that the dome is impervious to all forms of damage; a powerful, concentrated blast of energy, such as the Tailed Beast Ball is enough to disperse it, although the blood which composed it will remain, suspended in mid-air.
