One of Galko's friends, an Otaku with glasses who likes to mock Galko and gets constantly annoyed by her inability to wake up early. She likes to tell and ask Galko especially about suggestive topics. Between classes, Otako prefers to sit quietly and read. At home she watches anime based on her brother's recommendations.

The anime follows the everyday lives of three high school girls who are close friends: Galko, Otako, and Ojou. Galko is a slightly foul-mouthed but good-natured girl who is popular in her class. Her hobby is film appreciation. Otako is a girl who sits in the corner of the classroom, but for some reason is good friends with Galko. Ojou is an airheaded girl who often talks with Galko and Otako. 
 
Each of the girls' names refers to their type. Galko is a pun on gyaru or gal, which is a term used to describe a type of street fashion where women in their teens and 20s bleach their hair and wear highly decorated nails and a lot of makeup. Otako is a pun on otaku, and Ojou refers to a girl who is a daughter of a high-class family.

Galko-chan always speaks her mind, which may not be the wisest decision in all cases, but it’s never short of entertaining! Follow the exuberant and unbelievably busty high schooler as she traverses the ups and downs of adolescence with spirit and verve, alongside her best friends–the anti-social loner, Otako, and the unpredictably honest Ojou.
