Azuma Yunoki plays the flute and considered as a perfect third year honour student in the music department with a two faced personality. Though much more promising than his two older brothers, the role of the third son of the highly achieving Yunoki household restricts Azuma to surpass his brothers in academics or music.
Throughout history, Yunoki Azuma is shown having two sides in his personality, a 'Tender' personality to publicly show his companions and what we see from the beginning of the series, which is a charming and considered Prince character, and a 'Dark' personality that he shows to Hino Kahoko, this personality is similar to the one of an antagonist in a way that is misleading to all destinations in Hino when they are alone. He is assumed by Hino that the 'dark' personality is his true identity, but after meeting his grandmother and learn about the limitations and burdens stays at his family, Hino starts questioning if that is really the case.
