Sword of the Souls Desire

A specially made katana is made from a special seed that is kept under guard of Mitsukai Kihaku's clan. The seed itself is full of Yin Chakra, but is completely unresponsive unless it comes in contact with another person, in which case sucks Yang Chakra out of the person. When this happens, the seed will sprout into a sword that can be best used by the user, however the sword does not change shape when passed to another, it remains the same until it is destroyed. The only known users of the seeds are Mitsukai Kihaku, Arashi Kagami, Enkou Tsugumi, and gekizai Hyuuga.

In Enkou's case, the seed became a normal sword, but it had the ability to seperate the handle which inbetween becomes a face like structure that is capable of creating a high-pitched scream which can make an enemy's ears bleed, but the scream can be directed directly or it can be widespread, the sword can also release fireball like sculls from the face like structure on the handle.The Swords sound is that of a thousand screams.

In Arashi's case, the seed did nothing but become a hilt, but the hilt can direct all of Arashi's Lightning Release Chakra, into a condensed shapeshifting blade of lightning, similar to the Second Hokage's Sword. The sword sounds like static.

In Gekizai's case, the seed formed a small scalpel, but it also is a flute, at the end, which can be used to relay information to Arashi and Enkou. It can also be used to help syncronize and resonate the team, so they do not have to talk while they fight.
