Takanari Touguu

Shizumasa's older twin brother. Because of health problems, he is posing as Shizumasa as [Fake] Koutei, though no one knows this except Tōya (but later in the series Haine becomes aware of his "real" identity). In the beginning of the story, he is cold and distant but once influenced by Haine, he becomes more kind and soft. He, at first, hated Haine and thought she was annoying but then he grew to love Haine and wants her to become his. Takanari is the real author of the picture book "Shizumasa" drew. He hates his brother, who also turns out to be unpleasant. A slight difference between Takanari and Shizumasa is that Takanari's hair is more visibly darker than his younger twin brother.
