Wind Tunnel Technique

The wind tunnel technique was a seal invented by Miroku. Miroku had a high wind affinity, his chakra even took on very wind like properties. When he saw a Meiton (dark release) user suck in a chakra attack he wanted to due the same, hence the wind tunnel technique. Using his sealing skills he managed to create this technique and the seal does two thing. First, it uses his futon chakra to suck any chakra from a technique into the black hole that is really just the color the seal takes when it absorbs chakra. Afterwards it purifies the chakra and adds it to his own. As there is a goodside to this technique there is also a bad side. It will harm the user if it absorbs bijuu chakra or curse seal chakra and may hurt or even kill the user.
