In August 2023, Muchakai self-published a Chizuru-chan Development Diary compilation book. It included all 5 main chapters, 2 extra chapters, sketches and several illustrations, all printed in monochrome.

Since 2D Market previously published Chizuru-chan Development Diary Full Color in English, it was decided that it would be redundant to re-publish all five main chapters in monochrome just for the sake of matching the Japanese release. Instead, we decided to publish the two extra chapters, sketches and all the illustrations (now in full color!) as this “Extra” release.

Two extra chapters are “Bunny Training”, originally released as an 8-page booklet in 2014 and “Swap Battle”, a crossover chapter with Mako-chan Development Diary, making up the largest part of this doujin at 36 pages.
