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!

Even if they have a breakout as an author, marry the girl they love, and become a dad, people can’t change their stripes that easily (especially if they write novels for a living)—Itsuki Hashima is still writing and as wild as ever. Meanwhile, as his wife lovingly watches over him, his little sister Chihiro is growing increasingly tired of her unrequited love. Itsuki, Chihiro, Miyako, Haruto, Nayuta, Ashley, Kaizu, Kaiko, Setsuna, Nadeshiko—they’ve all changed (or not changed) to varying degrees over time, but what does the future have in store for them? The popular romcom ensemble series reaches its conclusion!

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!

Nayuta Kani gets serious. Itsuki and his friends want to believe they would never let confessions of love affect their relationships with one another. But beneath the surface, confessions change everything...Matters of the heart can alter the flow of a story, sweeping other characters up in the tide. Itsuki’s anime project is also making waves, but rather than add a refreshing twist to his life, it threatens to swallow him whole. Meanwhile, on a distant shore, Puriketsu continues his search for the girl with the “ass of the millennium.” Little does he know that a new development is about to flood his well of inspiration...!

A LOVE TRIANGLE'S ALL YOU (DON'T) NEED. Itsuki Hashima, the little-sister-obsessed author whose novels feature nothing but his favorite character trope, presses on through day after frenetic day, despite all his trials and tribulations. Deadlines, love, even his own family weigh heavily upon his mind-but when his friend Haruto Fuwa (still reeling from the awful anime adaptation of his series) discusses a potential love interest, the results could shake up Itsuki's entire social life. Will peace prevail?!

Mochizuki Touya has no time to rest. The fate of two worlds hang in the balance, after all. The Metal Devils, guided by Yula and seemingly supported by two mysterious twins, are on the rampage... They've mercilessly targeted the souls of people in both the world Touya knows, and the Reverse World! Armed with his new Frame Gear, Reginleif, will Touya be able to stop the malignant machinations of a wicked god? Fissures in space begin to crack, revealing a story of swords, sorcery, and a corrupted knight!
