Eitoku Academy received substantial donations from the families of the F4. As such, they were given free reign of the school by the principal and teachers. One day, Tsukasa Domyoji ordered the principal to expel Tsukushi Makino and Rui Hanazawa or he would cut off her family's money. The principal was reluctant to agree to expelling Rui, whose father was also influential. Tsubaki Domyoji then walked in and asked him to "ignore everything [Tsukasa] said." The matter was subsequently settled among the students themselves.
He was an older man, likely in his forties. His short hair was light-colored, perhaps grey. He also had noticeable wrinkles, small eyes, and thick, dark eyebrows. The principal was only seen wearing a suit.
