Tsukasa Suou/History

Early Years
As the heir to the Suou family, Tsukasa had a privileged but also rather strict upbringing. He was childhood friends with Tori Himemiya, who he often fought with. As children, Tsukasa sought the approval of adults by diligently trying to meet their expectations, while Tori shamelessly pursued his own interests and was regarded less favorably. This caused tension between them, but Tori's expressions of pity toward Tsukasa would also inspire Tsukasa to reflect on his own priorities.

Kohaku Oukawa was trained to do "dirty work" as part of the Oukawa family, a branch family of the Suou family, from a young age. Tsukasa and Kohaku met several times as children due to their relation. Once when they were children, Tsukasa protected Kohaku from a stray dog.

At some point before entering Yumenosaki, Tsukasa had an experience upon getting lost in the city. He wandered into different buildings, overwhelmed by experiences unfamiliar to his sheltered upbringing. After finding himself in a bar, Tsukasa came across a former idol, a retired member of Backgammon who sang of his regrets and warned Tsukasa not to wind up like him, a pitiful man who had betrayed his friends. Later on Tsukasa would consider this experience a life-changing one. He listened to the retired idol's CD when the pressures of being raised as the Suou heir caused him pain and self-doubt. Tsukasa suggests that this experience inspired him to take control of his future and pursue his own interests, which would later bring him to Yumenosaki Academy, and to Knights.

War Era
Tsukasa visited Yumenosaki, along with Tori Himemiya, when they were in middle school. During this visit, Tsukasa came across the remaining members of Knights left after Leo's departure. The three of them were practicing around the school's cenotaph, and although they seemed exhausted and quarrelled with one another, Tsukasa was drawn to the prideful way that they sang. This experience is what inspired Tsukasa to join Knights the following year.
