Aura

Aura is a special power used by the members of each of the eight King Clans. The aura a person uses depends on which Clan they belong to.

Etymology
Sometime long ago in history, there were seven Kings who lead their respective clans. However, for unknown reasons, a feud began between them and the clans separated, becoming enemies. Now, centuries later, the feud between the clans begins to escalate again because of a certain case regarding Isana Yashiro.

Types of Auras
There are eight clans in K, each lead by a King, which are represented by a color. They each have a unique aura.

Fire
All members of Homura possess this ability. This aura has a very destructive force to it, and can incinerate almost any and everything in its path. Depending on the use, its color varies from red to pink. It is shown that the flame aura doesn't harm someone who has what it takes to become a member of Homura, as Mikoto used his flames on Akagi, but it didn't have any effect.

Lightning
All members of SCEPTER4 possess this aura. This aura has the ability to strike opponents in quick succession and can attack multiple areas at once. Its color is blue.

Unknown Aura
Only the members of the seventh clan, who were lead by the former seventh King Ichigen Miwa, possess this Aura. When the user activates this Aura, it sends out a transparent purple arm that can reach long distances and attack enemies. It can also distort space and carry its user long distances.
