ABe next released two special "dōjinshi": the "Lifestyle Diary" and the "Extra Edition". The former explains that the story has been licensed as an anime to be released later that year, and so he will not be continuing the dōjinshi. The book's contents cover the specifics of character design, from personality to shoe-style, and lay out maps of the town and some of its buildings. It features several four-panel comics depicting the lives and behaviors of the specific Haibane, and the protagonist Rakka's curiosity about her halo and wings. The Extra Edition is a flashback story to the character Reki's experiences as a girl shortly after her mentor, Kuramori, left their home. This part of the story is covered in the anime, but the "dōjinshi" adds some additional detail. It was released after the completion of the anime series.
