The Mitsuya (三矢) Family is one of the Ten Master Clans, bearing the number Three (三) in their name. The current Head of the Mitsuya Family is Mitsuya Gen. [1]


They are part of Ten Master Clans, and are from the Third Institute, where the research focus was, "Control of Multiple Magics", the intent was to test the boundary of how many magics' could be activated at the same time as well as raising that boundary as part of their Magician Augmentation Project. [2]

The Mitsuya Family cooperates with the Defense Forces by gathering information in the East Asia. [3]

Business Ventures

Gen, the current Head of the Mitsuya Family is an international small-arms broker. [1]

It's difficult for Magicians to construct an overseas information network without being attached to a government agency, thus among the Ten Master Clans, only the Mitsuya Family is an exception, due to their ability to obtain information while conducting transactions with weapons dealers. [4]

Main House

The Mitsuya reside in Atsugi (Kantō, Kanagawa). [1]

The Mitsuya Family mansion is a short distance away from the Third Institute. The mansion has the latest magic training equipment that isn't any less inferior than that of the Magic High Schools. The training grounds at the mansion are for those who live at the residence. Out of respect to the Mitsuya Family, countless individuals refrain from training at the grounds and instead go to the Third Institute to train. Thus there are large spans of time when no one uses the training grounds. [5]

Area of Influence

The Third Institute while being in operation, is managed by the Mitsuya Family along with the Mikazuki Family, whom provide the know-how to magicians from the National Defense Forces. [1][5]


There are seven children in the Mitsuya Family, from Motoharu being the oldest son down to Shiina being the youngest daughter. [5]

  • Children :
    • Oldest Son : Mitsuya Motoharu (三矢 元治) - The next Family Head.
