Abilities
Myaku-giri is a sword of incredible craftsmanship which can stand defend against strongest of attacks. This ability alone would qualify it as an amazing blade, but it is not where the true power of this sword lies. Within the confines of this blade dense channels of chakra have been woven, which are the key to Myaku-giri's abilities. The aforementioned chakra is incredibly irregular in nature which causes it to dissociated most chakra in comes in contact with. As such this sword can be used to slice through chakra with much greater ease than a normal weapon. Also because of this unique quality Myaku-giri is impervious to weapons that are enhanced with chakra flow.

Unfortunately because this weapons constantly contains imbalanced chakra, it is impossible for a user to flow their own chakra through the blade in the same way they would another weapon. As such a user much readjust the balance of their chakra when using this weapon as a conduit for techniques. Though, if and when a user is able to master flowing chakra through this weapon they will be able to perform such techniques with greater speed and efficiency, because they will allow the chakra within the sword to aid in pre-molding the chakra that they channel into it.

It is currently unknown who forged this particular blade, though there are rumors that this blade has a sister sword that was forged by the Fuyutama Clan. Unfortunately, these rumors have never been confirmed and the current wielder Nōsei does not seem concerned with it.
