A spinoff of Ore no Imouto ga Konnani Kawaii Wake ga Nai following Kuroneko's route. This manga is a new story based on volume 15 and 16 of the Oreimo lightnovel written by the original author Tsukasa Fushimi. Not to be confused with Ore no Kouhai ga Konna ni Kawaii Wake ga Nai, which is a spinoff.

This is the Ayase route of the Oreimo storyline.

A "Eromanga-sensei" spinoff centered around the beautiful and famous young light novel author Yamada Elf. After failed attempts at seducing her dense siscon neighbour Izumi Masamune, she tries it with cooking.

Writing light novels isn't all that easy, especially when you're in high school and you have to do the cooking and the chores for your shut-in stepsister who's hardly come out of her room the past year! In the light novel business, it's crucial to have the right person illustrating your books to help them sell–and maybe get made into manga and anime! But in a world of online pen names, the author and the illustrator may still not even know each other . . . until one day they realize they've been living in the same house all along! Now the home life of confident writer Masamune Izumi and his reclusive sister Sagiri–aka the artist ''Eromanga Sensei''–will be a drama to compare with their rising careers, their restive fan base, and their rivals in the industry!

Ore No Kouhai ga Konnani Kawaii Wake ga Nai follows the experiences of Ruri Gokou and Kyousuke Kousaka, as they both begin to explore the feelings that they have for each other. Will they be able to acknowledge their feelings for each other, or will they reach a standstill in their pursuit of happiness?

A collection of artwork by several artists, 4-komas, omakes, and fanfiction stories of the Toaru Majutsu no Index universe. Original released as a bonus special edition of the release of the 5th manga volume of Toaru Kagaku no Railgun.

Kyosuke Kosaka, a normal seventeen-year-old high-school student, hasn't gotten along with his younger sister, Kirino, in years. For longer than he can remember, Kirino has ignored his comings and goings and looked at him with spurning eyes. It seemed as if the relationship between Kyosuke and his sister, now fourteen, would continue this way forever. One day, however, Kyosuke finds a DVD case of a magical girl anime entitled Hoshikuzu Witch Meruru (Stardust Witch Meruru), which had fallen into the entranceway of his house. To Kyosuke's surprise, inside the case, an adult video game entitled Imoto to Koishi yo! (Love with Little Sister!) is hidden.
