The origins of the Neighbors Club – and a few gender-bending secrets – are finally revealed! What on Earth will happen next!?

Sena takes Kodaka and Kobato to meet her father, Pegasus. They decide to spend the night - and lots and lots of awkward situations ensue.

It’s festival time! Kodoka talks to Sena about hair dye, and Yozora’s hair becomes a casualty of a fireworks display!

Yozora, Kodaka, and Sena try to bond over some co-op video game action. Unfortunately, the girls are way better at bashing each other than working as a team.

Kodaka tries to give Sena a swimming lesson, but some obnoxious guys hanging out by the pool make the situation even more uncomfortable than it already is. Luckily, Kodaka’s got Sena’s back.

When the Neighbors Club heads out to sing some karaoke, the whole group ends up divided between multiple rooms. Later, Yozora gets jealous when she hears that Sena’s dad wants to meet Kodaka.

The gang heads to Sena’s summer home, where they spend hours romping on the beach. Later, the group settles in for some ghost stories. Unfortunately, after the chilling tales, everyone’s too scared to go to the bathroom alone.

Yozora and Kodoka are loners at school. In order to make friends with other misfits, they start the Neighbors Club. Soon, a third member joins the club: Sena, a popular girl who annoys Yozora to no end.

The Club gets a couple of new freshmen members: Yukimura, who’s been following Kodaka around to learn some lessons in manliness, and Rika, an awkward young scientist.

Rika gets the group to play a new RPG. Of course, the gang’s manic dynamic is as much a problem in the virtual world as it is in the real one. Later, Kodaka must deal with a surprising new Club member.

With summer break approaching, the gang decides to use their cell phones to keep in touch. Sena decides to get the same model as Kodaka's - a choice which drives Yozora totally insane.

Kobato’s burning up, thanks to a busted A/C. Inspired by her favorite anime, she decides to wear more season-appropriate attire. Later, the Neighbors Club heads to the pool to cool off.
