Kazumi Yukihira

Nothing much is known about the High School Principal, but he is one of the people who opposes the Elementary Division Principal. He hates and opposes the Elementary Principal because he has also hated being used by the academy as he has had no outside contact and has lived in the academy since he was young. In addition to the fact he supports Mikan and Yuka, he is willing to stop the Elementary Principal and his plans. He protects Mikan secretly. Once Mikan got caught by the academy, he instructed Goshima to save Mikan. In chapter 99, Mikan, Natsume, Hotaru, Ruka and Narumi are being chased by the elementary school principal, but the High School Principal helps them. He is actually Mikan's uncle and the older brother of her father. He revealed the history of her father and Yuka Azumi to Mikan, further shocking Mikan. He actually feels guilty for the death of his younger brother because he was the one who had introduced Izumi to the academy which brought his death. Kazu cherished his younger brother the most. He has two Alices; one of them is the power to detect other people's Alice upon sight, either in person or via photographs, the other, "longevity", grants him a long life and the ability to not appear to have grown old. Because of his Alice, he is regarded as a "god" in the academy. (Source: Wikipedia)
