Junsuihauru

Junsuihauru (純粋ハウル; Literally meaning "Pure Howl") is a large, green nodachi with special properties made by Yokumensu. A flag a large banner is tied to the hilt representing the Kajiya Clan with it's emblem.

It is made of a metal that absorbs Chakra in a certain distance, giving it the ability to negate ninjutsu by literally slicing through an opponent's techniques, in spite of whether the chakra has been transformed or not and even prevent them from being performed by absorbing all of the necessary chakra, before preparations can be completed. Another one of it's abilities is actually sealing one's chakra. When the blade comes into physical contact with an opponent, it has the ability to temporarily seal one of the Eight Gates which allows chakra to pass throughout the body for about 9 hours. In other words, if hit in the 8 correct areas one's chakra can be completely sealed away for almost three days total. Because he discovered remnants of Ryūmyaku Chakra, he is also able to use Junsuihauru to directly slash through time itself. This releases an echoing sound of wolves howling, hence why it is named.
