Shizuka Nanami

is a Senior at St. Ishiyama Academy, and a member of the Rokkesei. She is an old friend of Tojo, and both knew Saotome in the past. She's also the only female member of the Rokkesei, as well as the captain of the archery team and the student council vice-president.

Apprearance
She is an average heighted young woman with long orange hair, which is spiked out on several ends. She wears three hair clips on the left side of her hair. Shizuka is often seen wearing her school's uniform.

Abilities
Her actual fighting skill is as of yet undetermined, but Kunieda was surprised that she could reach the rooftop undetected by her, and both girls rose up to help Oga and Mikki against Teimou, which indicates Shizuka is as unafraid of physical combat against men as Kunieda. She can feel Saotome using his demonic powers, which shows she has notable strength for a human.

Kaname Izuma
She seems to have a strong relationship with Izuma as she is able to joke and laugh with him, something the other horsemen seem unable to do (likely due to their fear of him). She is seen massaging Izuma's back after their volleyball training session.

Hidetora Tojo
She knows Toujou from the past and calls him Tora, and both are longing to meet Zenjūrō Saotome. It is also said by a few people that she might have romantic feelings towards him, as in the anime where when Tojo goes to fight Izuma, she screams when Tojo got hit badly.
