Aura

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

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

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

Trivia

 * A clansman is not obliged to obey the King. Transferring from one clan to another is possible. However, it's usually considered that a clansman is bound only to one type of Aura, while the Aura of his previous clan vanishes after the transfer. Exceptions do occur, as Reisi Munakata is surprised that the Red Aura remained in Saruhiko Fushimi, even after he received his Blue Aura.
 * Kuroh Yatogami is also able to manifest Colorless and Silver Auras, along with Yukari Mishakuji (Colorless and Green Auras).
