Akira Yoshii (吉井 玲 Yoshii Akira) is a supporting character in the Baka to Test to Shoukanjuu series. She is the older sister of Akihisa Yoshii.
Akira is a beautiful young adult woman with short black hair (dark brown in the anime), dark brown eyes and busty, slender figure that makes Mizuki Himeji, Minami Shimada and even Shouko Kirishima envy.
When at home, she wears a black and white shirt, blue pants, and cross choker around her neck. When she first appeared, she wore a white bathrobe that appeared to be too small for her.
Despite having a Harvard graduate in education, Akira is horrible at cooking  as revealed when Akihisa Yoshii finds the attempted Paella dishes in the fridge and remembers the band-aids on Akira's hands. She strongly lacks common sense, as shown in the anime when she changed into a bathrobe while inside a train with other people just because she was sweating. Akira seems to have a huge brother complex as she repeatedly tries to seduce her brother into kissing, or at some point taking a bath with her. She will reduces his allowance of her own volition. She blushes extremely red when Akihisa admits that he loves her as a sister.
Both her and her brother are complete opposites in terms of their skills: Akira is smarter and much more perceptive than Akihisa, but is a terrible cook, while Akihisa is an idiot but is a much better cook than Akira. She is seen by Mizuki Himeji and Minami Shimada as someone to greatly admire and to be jealous of , although it can be attributed to her beauty, it is mostly because of her E-cup breasts (Minami) and her slim figure (Mizuki).
Akira is smart but a terrible cook while Akihisa Yoshii is an idiot but a good cook.
