Name: Kotaro Bokuto. Height: 185.3 cm. Birthday: September 20th. Grade: 12th Grade (3rd Year). Jersey Number: 4. Personality: The energetic ace and captain of the team.

Name: Keiji Akaashi. Height: 182.3 cm. Birthday: December 5th. Grade: 11th Grade (2nd Year, Vice-Captain). Jersey Number: 5. Personality: A calm, collected, and highly intelligent setter. He is the team's strategist who analyzes Bokuto's moods in detail and controls the team with exquisite handling.
