Upon starting high school, Wakaba Kohashi, a rich girl wishing to be a gyaru, makes friends with her classmates, Moeko Tokita, Mao Kurokawa, and Nao Hashiba.

Wakaba becomes excited about going to get ice cream with her new friends.

Wakaba buys a galge under the impression that it is a game for gyaru, with Nao lending her one of her own games.

Wakaba and the others go to Moeko's house, where they decide to make some cupcakes, only for Moeko to do everything herself.

Mao feels downhearted when a boy she kind of has a crush on appears to be interested in a girl from a rich school, so she decides to observe Wakaba in order to pick up her rich girl mannerisms.

The girls go to the pool together, with Wakaba borrowing a swimsuit from Moeko. Afterwards, Wakaba laments being unable to go to a summer festival due to her curfew, so the others come up with a plan.

The girls manage to convince Wakaba's mother to let Wakaba attend the festival with them, allowing them to enjoy the stalls and fireworks.

Wakaba's class prepares a play for the upcoming culture festival while Nao sets her sights on the beauty pageant.

Nao catches a fever on the day of the culture festival, so Wakaba takes her place in the beauty pageant, managing to win first place.

Moeko attempts to overcome her struggles with sports by trying to perform a back hip circle on a bar.

The girls have a sleepover at Moeko's place during New Year's so Wakaba can have her first shrine visit with her friends.

Wakaba enjoys her first snowfall by participating in a snowball fight with the others, though ends up catching a cold in the process.

Wakaba worries that she might be moving abroad with her family, so the others try and convince them to stay, soon learning it was just a misunderstanding on Wakaba's part.
