Aura

Aura is a special power used by the members of each of the seven 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 Yashiro Isana.

Types of Auras
There are seven clans, each lead by a King who is represented by a color. They each have a unique aura.

Red Aura
All members of HOMRA 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 sometimes the flame aura doesn't harm someone who has what it takes to become a member of HOMRA, as Mikoto used his flames on Akagi, but it didn't have any harmful effect.

Blue Aura
All members of SCEPTER 4 possess this blue colored aura. This aura has the ability to strike opponents in quick succession and can attack multiple areas at once, they are also able to draw their aura into their swords for combat.
