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