ミサキ老人

Elder Misaki is a mysterious presence at the research center. He is a very powerful psychic with unspecified abilities. He erected the mystical barrier around the research center. This barrier was sensitive to individuals and kept specific people out and others inside its limits. The barrier disappeared upon his death at the beginning of the series. It is certain that Elder Misaki had the power of foresight and Mikuriya, the Kirihara brothers and Shouko hold him in high regard.
