Earth Release Barrier: Earth Prison Dome of Magnificent Nothingness

This jutsu traps the victims inside a self-repairing dome of earth which is almost instantaneously able to reform, even after Kiba hit it with his Piercing Fang. Jirōbō was able to absorb the chakra of anyone trapped inside, something he enjoyed greatly. However, Jirōbō's chakra was distributed throughout the dome, but not equally. Near the back (relative to him), his chakra was much weaker, making the dome weaker in that spot.
