The weekly chart between August 29 and September 4 for COMIC ZIN is topped by Aoki Hagane no Arpeggio Volume 23 which is already discussed in the TSUTAYA post for the same week, so be sure to read about it right here for further information.
As for others, they are all new series except for Number 4’s Dasei 67 Percent Volume 9 which slipped 3 spots to Number 4. At Number 2, you will find Shuumatsu no Harem: Fantasia Volume 11 in its first 3 days while its related title, Shuumatsu no Harem is 3rd with its 16th volume. As for Shuumatsu no Harem: Fantasia, this is not its first time on COMIC ZIN’s chart as it was last seen back in January with its 9th volume. Unfortunately, the series still has a hard time penetrating Oricon’s Top 30 charts since the Blog began tracking. The same however, cannot be said for its main series. Shuumatsu no Harem has been consistently appearing with its volumes, though its physical sales performances on Oricon’s Top 30 sales charts have not been as good as before. To compare, it sold 61,033 copies for Volume 11 in its first 5 days whereas Volume 15 was charted at 7 days of sales but sold only 40,189 copies. More information about the works can be found on its official website right here whereas the Manga can be read for free in Japanese for the main series here and for Fantasia here. According to the volumes’ latest covers, Shuumatsu no Harem as a series has passed 8.5 million copies in circulation. Out of that, 1.5 million copies belong to the Fantasia series. It was also adapted into an 11-episode TV Anime series in October last year by Studio Gokumi and AXsiZ.
Next, at Number 5 is Kirara Fantasia Volume 4 in its first 4 days, its first time on COMIC ZIN’s list, and it has never been featured on Oricon’s Top 30 since the Blog started tracking. More about the work can be found here on its official web page while some of its Manga chapters can be read for free in Japanese here. In August 2017, it was adapted into a 13-episode TV ONA series. Right below is Kashimura Ikka no Yoake by authors Hoshi Okamura who worked on the 2019 Manga, Tentacle and Hiroaki Samura who is known for his work, Blade of the Immortal. You can read the preview of Volume 1 right here via Booklive in Japanese.
