Itsuka Clan

The Itsuka clan is the current royal clan of the Tsaesci. They are considered the most powerful among the six clans descended from Nozomi Itsuka, the one who brought the clan to power.

The Itsuka clan is ancestral to all modern members of the Five Guardian clans, namely the Hoshimiya, the Shiragane, the Onigawara, the Akashi and the Mikogami.

Trivia

 * The name "Itsuka" is inspired from the Date a Live anime, and means "Five Streams". This is very appropriate as there are five elements in the traditional Chinese Wuxing, the Itsuka Dynasty is the Fifth Dynasty and also because the Itsuka clan is the progenitor of the five Guardian Clans.
