UPDATE: Offically not being drip fed by the original uploader anymore, the book is done.

Archived from here: https://www.kishisdoujinshicorner.com/category/doujinshi-translation/day-garma-died/. The table of contents, back cover, advertisements and additional cuts/bylines appear to simply not be included, though translations are provided. This doujin follows the life and times of Garma Zabi and his eventual fall, told through the perspective of several fujo authors of the late 70s to early 80s. Given information already out about the circle, this group seemingly only joined together to create this singular book. Otherwise, many of the members are from the Let's Play Around With Char circle with additional members from NORMAL, REX and Corporation Shameless. As noted with other works like so, lavender covers typically connote BL/yaoi.

Additional context:

This book is often noted to be released around 1980, however, this is now debunked thanks to information found in this work:

https://e-hentai.org/g/3236076/fbfaa74b9a/

Given that there are no immediate dates given otherwise, Feb. of 1981 is/was its definitive release. Sold via mail order, this work did not make it to Comiket.

Scans are adequate until this book goes to auction/restocks elsewhere. Should I find it, I will rescan the entire book in better res with all info.
