A show off girl named Aya ends up losing her panties somewhere and tries to steal panties from her classmate Konatsu before she's discovered.

Aya develops hiccups, so the others try to help cure them.

Aya is fearful of her older sister, Saya, and her gang leader boss, Kaname Oku.

As Aya's secret underwater plans are thwarted by Asuka Utsunomiya, she almost drowns and ends up having her first kiss taken by Kaname via CPR.

When Aya gets sick with a cold, Asuka comes over to nurse her back to health in her own unique way.

Aya comes up with a crazy scheme to try to get Asuka to smile.

Konatsu gets a lot of Matsuzaka beef, prompting Aya to have a yakiniku party which gets a few uninvited guests.

Aya contracts amnesia after slipping on a banana skin, so the gang work together to try and bring back her memories.

Aya misunderstands a conversation between Konatsu and Ai and gets into a heated debate with Minami about who's more 'appealing'.

The girls attend a masquerade ball where everyone besides Ai ends up under the influence of the 'juice' being served.

Minami is due to return to LA, so the girls set off some fireworks to see her off.
