Summary
Hajime Kokonoi, commonly referred to as Koko, served as the commander of the 10th generation Black Dragon. He appeared as a fifteen-year-old in the past, aged to twenty-seven in the future timeline, and reached eighteen years old during the final arc. Born on April 1, 1990, with blood type A, he stands 174cm tall and weighs 60kg. His appearance is defined by black hair styled in a deathhawk, with the right side flowing wildly over his face and the left side featuring shaved rectangular patterns. He possesses fierce, piercing black eyes and tall, arching eyebrows that give him a perpetually angry expression. His wardrobe often consists of elaborate attire that coordinates with the detailing on his golden earrings. Koko perceives the world through a lens of constant calculation, acting exclusively in his own self-interest. He aligns himself with individuals who possess power but abandons them the moment they lose their influence. While he appears materialistic, his drive for money stems from deep-seated despair. In his youth, he fell in love with Akane Inui, but she was severely injured, and her family could not afford the necessary medical procedures. Realizing that illegal activities were the only viable path for a young boy to accumulate wealth, he began hiring criminals to commit crimes for him. Over time, he became consumed by the pursuit of money itself, ultimately forgetting his original motivation to save Akane.
