Hutijin

This is a very powerful technique that takes advantage of the corrupting nature of Asu's chakra. It is said that in tales of old that Asu, through his dark chakra, transformed the Sage of Enlightenment into a Demon and caused the members of Thesmophoros to turn amongst themselves, respectively. However, this technique is not intended to elevate the power of a target, but to diminish it.

For this technique Asu will collect a large store of dark chakra into his palms. After performing several hand-signs, which are not usually necessary, his hands and forearms will begin to pulsate with what appears to be black and red lightning sparks, merely a sign of the intense chakra being collected. This chakra can be channeled into whatever Asu touches, flooding his chakra into the body of another. Instead of adding to the chakra pool of the other, the invasive dark chakra will corrupt the body, debilitating it as it destroys matter. This technique can be easily used to kill, and this death becomes instant when pressed against major parts of the body.

However, the chakra spread throughout any network it is channeled into, and so it can also kill if channeled into an arm so long as contac is maintained for a short time. This technique also forms a strong defense against modes of chakra absorption targeting Asu, as the chakra freely and quickly flows into the absorber without requiring Asu to make contact, as it uses whatever mechanism the opposing technique employs to deliver the corrupting nature.

A death grip can also be employed by the Rashoujin clenching down with his palm in the direction of the infused target, which will cause sparks of black and red chakra to pulsate all around the target and bring them to their knees. This grip is similar to moves as Desert Coffin, though its pressure is more metaphysical than physical.

The down side to this technique is that it will strain Asu's heart, causing severe damage if misused.
