Yoshiko Hanabatake (花畑 よしこ Hanabatake Yoshiko) is the main protagonist in Aho-Girl.
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. She usually wears her school uniform.
Yoshiko is a complete idiot that is addicted to bananas, to put it simply. She is an eccentric person who is also very annoying towards Akuru Akutsu, even though she truly wants him to love her. Yoshiko even goes so far as to let him see her panties. Yoshie Hanabatake even goes as far as to beg Akuru to be her boyfriend. Her idiotic actions towards Akuru caused her to get physically assaulted by him. Akuru went as far as to punch her so high in the air it literally knocked her out. She downright annoys him. As a result of stupidity, her social skills are beyond abysmal, and generally make the worst first impressions.
Yoshiko is quite perverted, as she enjoys groping the disciplinary committee president's breasts, has sneaked into Akuru's room and started sleeping around him, and likes to peek in the men's room just to see Akuru.
As a child, she showed a strong proclivity towards great agility and speed. She is strong for a girl despite her petite stature, as when she carried Akuru with little to no effort above her head when they were children. She can jump from one balcony to another, and is shown to have fast reflexes, with the exception of Akuru’s fast punches. However now she gets hit more often 10 years later, since she’s too idiotic to see it coming.
Yoshiko is in love with Akuru ever since she was a child and they were childhood friends, but Akuru doesn't see it that way, he sees Yoshiko for what she is - a worthless idiot.
Sayaka is Yoshiko's closest friend. They become friends after Yoshiko told her that Akuru had no friends. She tried her best to be friends with Akuru to no avail.
Yoshiko dislikes Fuuki and sees her as a potential rival for Akutsu's attention (though the boy has no interest in any of them whatsoever), but this doesn't stop her from occasionally fondling the latter's breasts, mostly as a means of provocation.
- The given name Yoshiko is a female variant of Yoshi, which happens to be a unisex Japanese name; the surname Hanabatake means "flower patch", "flower bed" or "flower garden".
- Yoshiko has been beaten by Akuru Akutsu on countless occasions, and has some nerve saying words that actually trigger specific people.
