Yoshiko Hanabatake is an idiot beyond all belief. Somehow managing to consistently score zeroes on all of her tests and consumed by an absurd obsession with bananas, her senseless acts have caused even her own mother to lose all hope. Only one person is up to the task of keeping her insanity in check: childhood friend Akuru "A-kun" Akutsu.
Yoshiko is a fair-skinned young girl who has an average bust. She has straight waist-length light brown hair that is tied into two high twin tails along with forelocks near her ears and reddish-brown eyes. Her skin and hair are very well-cared, because she wants to look good in Akuru Akutsu 's eyes.
