Tsukasa was a prime minister at a young age, despite his father's corrupt leadership and absolute power. His father used dishonest methods to provide for the family, but Tsukasa disagreed with his actions and exposed his wrongdoings, leading to his execution and disownment by his mother. Despite this difficult upbringing, Tsukasa remained friends with Masato and Shinobu from childhood. He prioritized helping others over himself, family, friends, and associates. After conquering the empire, he took charge of politics to prevent war. Additionally, Tsukasa had heterochromia. This information can be found on Wikipedia.
