"Imouto sae Ireba Ii" (all good as long as we have younger sister) volume 6 by Hirasaka Yomi. This volume answered all the confession scenes from previous volume, plus backstage stories of how anime production works.
Volume 5 might have been written to setup Miyako as the main heroine, but that plan failed early on in this volume. Despite the newly created love triangle, all characters were able to get through this awkward situation with another round of tabletop RPG. All this time I was wondering if that recurring RPG session had any real purpose, and looks like it had been planned for just this situation. Seems like most other recurring features (such as the detailed beer tasting notes) are still just fluff, although they are still entertaining.
One recurring feature that is well appreciated are these insider tales of the novel industry. In this volume, we had an audition process for Itsuki's upcoming anime series, followed by a cast selection process that largely ignored those audition results. Everyone understands that there are lots of business decisions involved in casting, including event appearances, deals with sponsors, and general scheduling risk, but it was still frustrating to follow. This chapter follows the recurring conclusion of "this is terrible, how did we end up in this situation?", although later chapters managed to make it a more positive outcome. This was the highlight of this volume.
Despite being a series about younger sisters, Chihiro has been making fewer and fewer appearances. Only so few pages in this volume and it involves that perverted illustrator. I hope we see more of Chihiro in future volumes.
Unrelated to the book itself, the ad inserts that came with these novels included a board game this time. This board game includes a good sample of the various events that occurred in earlier volumes.
