Sora

Sora (ソラ; literally meaning, "wind") is the an elemental ability that was normally used by the deceased members of the Masahige family. It was made from a contract of the wind god to which had the same name.

It was seen as very destructive as it could rip through any object, acting as a sword for strong clan members. However, later on their years of life, the Masahige could only channel Sora through their swords, to amplify their own strength. The last Masahige known to have been able to use Sora through his own body was Kū Masahige.
