Miyafuji Yoshika (宮藤芳佳) is the main character of Strike Witches. She has short brown hair and wears a school swimsuit under her blue school uniform. She is a part of the 501st Joint Fighter Wing. Her affiliation however is the 288th Fuso Air Force, along with Sakamoto Mio.
Her first Striker Unit was a A6M3a type Zero with a single yellow stripe as it's identification stripe. Her second unit was the same type (previously owned by Major Sakamoto Mio until she received a new unit based off of the Kawanishi N1K-J Shiden (Violet Lightning)) with blue stripes on the vertical stabilizer as well as a blue angled stripe that points downward at the front and upward at the back.
Her third (and current) striker unit is based on the Kyūshū J7W Shinden (Magnificent Lightning). The Shinden allows Yoshika to use her magic to her fullest potential, as during episode 8 of the anime (Strike Witches 2) her magic became so strong that the governor installed on Mio's striker unit protected the magic engine from overloading.
Her familiar is the shiba inu.
She has been shown to be attracted to other witches' breasts, especially Lynette Bishop's. Because of that she was given a nickname 淫獣宮藤 (injuu miyafuji, lewd/dirty beast Miyafuji).
