Family Relationships * Views the Eldest Son, Ichiro, as Absolute He worships his older brother Ichiro from the bottom of his heart, and being praised by Ichiro is his greatest joy.

Mental Independence and Growth * Awakening as an Individual At the beginning of the story, he was dependent on Ichiro and tried to prove his worth by putting Jiro down. However, through battles with various adults and team crises, he has moved out of his brother's shadow, faced his own strength, and grown rapidly as an independent rapper. Saburo Yamada is the youngest member of the team—a precocious, sharp-tongued genius boy who captivates many fans with his pure love for his brother and his story of mental growth.
