Even though Sasaki's droll corporate life is constantly filled with work, it leaves him tired and unfulfilled at the end of every day. In search of some companionship to fill the emptiness in his life, he visits a pet shop on a whim, not realizing he's about to change his life forever. After settling on an adorable bird and bringing it home...his new roommate reveals that it's actually an incredible sage from another world who promptly bestows Sasaki with supernatural powers as well as the ability to cross between worlds. All Sasaki wants to do is use these newfound powers to live in peace and comfort, but there are more than a few colorful characters who might get in the way of that...

When Sasaki brightens up his tired corporate life by buying a pet sparrow, he never imagined the bird would actually be a reincarnated sage from another world! With his new avian roommate teaching him all sorts of magic tricks, could this be Sasaki's chance to escape his droll office job?

Sasaki's pet bird (and otherworld sage) Peeps has bestowed him with powerful magic and the ability to cross between worlds, all in order to game the system and live the good life. But due to unforeseen circumstances on both sides, things are not going as planned. Sasaki's job as a government psychic is not all it's cracked up to be, and with a magical girl out for blood, a neighbor giving into dark temptations, and a former enemy changing sides, Sasaki and Peeps are looking at a big traffic jam on their road to success!

Even after making his break as an author, marrying the person he loves, and becoming a father, Itsuki Hashima has not changed and continues his regular routine of writing novels. But how about Chihiro, or Miyako, or Haruto and Nayuta and Ashley? Not to mention Kaizu, Kaiko, Setsuna, and Nadeshiko?! How much or how little have they changed? What kind of future awaits them?

Winter ends, spring arrives, and our protagonists take a new step forward. Haruto announces a new series. Miyako joins Branch Hill Publishing to finally become a professional editor. Chihiro becomes the life of her university's TRPG club. Finally, a 100,000-character love letter inspires Itsuki to pour more energy into his novel and become a genuine protagonist. A new everyday life dawns as the series enters the first half of its final chapter!

Thanks to Peeps getting a little lost in the sauce, the existence of the base that Futarishizuka established is leaked online! Without a way to point the finger at anyone in particular, the situation quickly erupts into chaos. Meanwhile, Sasaki gets a new assignment. And this time it's...dealing with a giant monster in the Pacific Ocean?!

Itsuki and Nayuta are finally together, successful in both love and work-but they're not the only ones facing big changes as the Christmas season approaches!

After giving up on becoming a protagonist, Itsuki continues to listlessly churn out novels like a machine. On the other hand, Nayuta has given up writing entirely in favor of shutting herself up in her room and playing video games. Though our main characters have stagnated, the world keeps turning and time marches relentlessly forward...and whether they're aware of it or not, big things are in store for Ashley, Nadeshiko, and the Hashima family.

Just as he's getting used to his new life of world hopping with Peeps, a run-in with a psychic forces Sasaki to make a sudden career change--to the top-secret Paranormal Phenomena Countermeasure Bureau. Just how many double lives can he handle?!

As the 16th annual GF Bunko New Authors Contest approaches, Itsuki's girlfriend Nayuta gently supports him while a major slump is preventing him from writing any novels. Toki and Miyako try to find a way to snap him out of it, but the results are anything but good. Meanwhile, Chihiro undergoes a huge change now that she is no longer hiding her gender...

Chihiro's big secret is finally out, and Itsuki is predictably thrilled at the news. With a girlfriend and a sister and a successful career, his life is complete. And now that Chihiro has been freed from her burden, will this be a turning point for her...?

When Itsuki Hashima's friend and fellow author Haruto comes to him for love advice, Itsuki's relationships begin changing, too-throwing his life into disarray as he juggles deadlines, romance, and family issues! And when the dust finally settles...

Sister-obsessed author Itsuki Hashima is embroiled in a bitter struggle with his popular series Sisterly Combat. Between video games and mixed baths and cherry blossom viewing and making up excuses for his editor, he's slowly but surely making progress on his manuscript. Somehow, he and his unique collection of friends--Nayuta Kani, Puriketsu, Miyako Shirokawa, and his little brother Chihiro--manage to stumble through life together. And not only that, but his friend Haruto's series has finally gotten an anime!

The gang gathers at Itsuki's to celebrate the premiere of his new anime! Naturally, tensions are high since it could be a flop, but they can't help feeling excited anyway. Between tentacles, maid outfits, and a confession of love, it's business as usual for our favorite light novelists!

As always, Sasaki and his pet bird (and otherworld sage) Peeps continue to leap across worlds, trading goods for a profit. Thanks to a little help from Futarishizuka, they've found a way to exchange otherworld valuables for modern currency, and Sasaki has been studying up on magic, making him unstoppable against psychics and magical girls. All that's left is to make as much money as they can, retire, and start relaxing'AEibut that won't be so easy. In Peeps' world, the dispute over succession begins in earnest, and back home, the psychic battles never stop. Not to mention Sasaki's neighbor, who is caught up in an angels-vs-demons death game. As worlds collide, Sasaki'AEos in for even more chaos!

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!

The winners of GF Bunko's competition for industry newcomers are finally having their works published, but some of the rookies are faring better than others. Meanwhile, the All About My Little Sister anime adaptation is facing its own share of troubles, Miyako is considering her future career path, and Chihiro has finally found a rival...?!

It's a new year, and the anime for All About My Little Sister is steadily proceeding. But when the news is leaked early, how will GF Bunko recover-and who will take the fall...?!

Miyako has gotten a part-time job working in editorial, thanks to the recommendation of Itsuki's editor Toki, but she had no idea how much work it would entail. Wrangling manuscripts from troublemaking authors, modeling for manga (in the nude), providing inspiration for Nayuta (in the nude), drinking parties, ridiculous demands from authors and editors... How will she hold up?!

Itsuki Hashima's spirits are high after learning one of his many little-sister-filled series is getting both an anime and a manga adaptation! However, the manga artist he'll be working with has a shocking secret...
