The eternal rivals Sena and Yozora face off on the basketball court, where Sena dominates all other players with her power, speed, and technique. What does Yozora have up her sleeve in this fight? When Christmas Eve arrives and the club members attend a school holiday party, they each have their own hopes about how things will unfold...but the events that await are even harsher than they might imagine.

Meet the Neighbors Club—an unfortunate group of even more unfortunate people trying to make friends by doing things like playing bishoujo games and trying their hand at acting...to no avail. Existing members Mikazuki Yozora and Kashiwazaki Sena (two beautiful girls to be avoided) and Kusunoki Yukimura (a boy dressed as a lovely—and female—maid) are joined by a young nun and a girl genius who push all the limits. How will this affect Hasegawa Kodaka (the only one with common sense, although that doesn't mean he has any friends either)? And then there's his little sister, with a look in her eyes that says she's hatching a sinister plot...!

It's been a month since the misfits of the Neighbors Club joined forces to make friends, but now it's summer break and not one of them has had a shred of success. Rather than face the summer alone, the club heads out to the pool, where they can beat the heat and hang out together as practice for when they have real friends. What could possibly go wrong?

Ten years ago, Kodaka's best - and only - friend was a kid he knew only as "Sora." Now he finally knows that Yozora and Sora are the same person, but that doesn't mean their friendship can pick up where it left off. And to make things more complicated, she's known who he was all along... and chose not to tell him. Despite all that, life in the Neighbors Club continues as always. There are elaborate new hairstyles to try out, and new kinds of anime to explore! It all sounds normal enough, but if there's one thing you can count on with the Neighbors Club, it's that "normal" does not apply!

The Neighbors Club may be a group of friendless misfits who can't get the hang of socializing despite their best efforts, but at least they have each other to practice on! Sena's continued attempts to make Kobato love her result in the entire club taking an outing to an amusement park, where they turn a death-defying roller coaster into a competition, while eating curry and... getting kidnapped by demons?! But there's more going on at the club these days than meets the eye. One of the girls has a surprise in store for everyone - including herself! And when Kodaka challenges Rika to make a truly impressive invention, the skeleton he and Yozora have been hiding may not stay in the closet for long!

Kodaka's life hasn't been easy since joining the Neighbors Club. Getting dragged into a conversation by another strange nun was the last thing he needed. Then again, her advice seemed sound, until he discovered she was seriously twisted. Now her close ties to another member of the club will make it even harder for Kodaka to escape her. At this point, however, Kodaka is used to not being in control of his destiny. Whether it's studying with Sena (and discovering an unnatural obsession!), or having Maria invade his home to fight with Kobato, Kodaka's learned to go with the flow. Of course, this may not be the best approach to life, especially when it seems like other people are calling the shots for him!

Tomoko’s suspension is finally over, and all her friends are waiting! With the final summer vacation of high school just around the corner, she’s determined to spend it studying to get into Aogaku, the same college as Katou...but before that, it wouldn’t hurt to hit the arcade, would it?

The Okinawa training camp continues to be a rollercoaster of shenanigans, now with a curious misunderstanding threatening to shake the dynamic of the club members’ relationships… And at last, the Miyakojima tradition of otori begins! Will the springtime of youth finally grace the nude diving comedy?!

Hachiman Hikigaya is a cynic. He believes "youth" is a crock-a sucker's game, an illusion woven from failure and hypocrisy. Unsurprisingly, he's not the most popular guy. Meanwhile, there's Yukino Yukinoshita-brilliant, beautiful, and chillier than winter in Antarctica. Would you believe she's not exactly beloved by her classmates either? The unlikely pair gets forced into a club dedicated to helping solve their fellow students' problems. But will an ice queen and a screwup really be able to help anybody?

Itsuki Hashima is a novelist who's hopelessly enamored with the idea of little sisters and is constantly surrounded by colorful characters. A world class genius and love-guru who's beauty almost seems a waste on her. A girl who's constantly troubled by her friendships, love interests, and can't even find refuge in her dreams. A ridiculously talented illustrator. Each of them have as many problems and worries as the next and they never have a dull day together as they play games, travel, and work together. From the same author of the famous I Don't Have Many Friends, Yomi Hirasaka!
