Seigan

What they are
A Seigan is a Being with Arcana of Wind, and they have white hair and blue eyes.

It is normal for them to hide their power, and one is able to sense other Seigan around him. Often, they are clad in white or silver, but Shiro; the Snow - Haired Icy - Eyed Specialist chose black and red in his love for Shana. Normally, Seigan do not get along with each other, and one ends up killing the other.

Normally, their weapons are made up of wind, and therefore invisible.

What they can do
Most beings with Arcana are able to set a Deadlock, a seal to hide themselves from commoners (normally humans) who are oblivious to the truth of the worlds. They normally have ring decorations with two or three ribbons tied up on them, and it is not unusual to have the power to control wind or fly.

Seigan have marks showing that they are Seigan that glow, called Seigan Marks. Seigan Marks can be duplicated onto other beings by touching the Mark onto desired place, and appear the exact same as the one duplicating. Each Seigan Mark serves a different purpose, like recording, sensing or communication that the original owner may choose. Shiro had chosen all four when duplicating onto Shana; the Flaming - Haired Burning - Eyed Assassin, and he and Shana were always connected. When they split up, the Marks stopped glowing and had become inactive. They had started using them after reuniting. Beings who have Marks duplicated onto them cannot choose the purpose, although the Seigan who had duplicated it may.

Most female Seigan have their Seigan Marks on their backs, and they are more elaborate and larger than a male Seigan's.

Male Seigan have their Seigan Mark on their upper chest.

Seigan call upon their weapons which form through the Arcana.
