Chiaki Nanase

Chiaki Nanase is an intelligent, beautiful, and emotional girl that's the complete opposite of Taison. She cares deeply about him. Many of the characters fall in love with Chiaki during the manga, much to Maeda's annoyance as he has severe jealousy issues. One of her best friends from her childhood was Yakushiji, who is now one of the "Heavenly Kings" of Tokyo. She is head of the sport's committee in Teiken High.
