Transformers: All Spark (Manga series; 2012-2013).
From The Lost Media Wiki
looking for a seemingly lost transformers manga series. issue 1 is well documented and translated but I've been unable to find the following 11 issues. Transformers: All Spark started releasing in nov. 2012, in the (now defunct) shonen magazine "KeroKero Ace". Its final chapter was included in the magazine's final issue, in Sept, 2013.
10 issues and a standalone 2 parter released between chapters 4 and 5, were released according to the TFWiki, but i've been unable to find other references to back that up. there was also supposedly an ebook rerelease in 2017 via DMM.com (a japanese online retailer) but i've been unable to access this page if it still exists, even with a VPN. Several links were posted to twitter, but due to its link truncation, i cant see the FULL url, and therefore can't check the wayback machine. clicking these links directs to the website's library page. Hero-X were responsible for the reissue/collection, according to tfwiki. TFWiki has character lists and appearance counts, alongside single images for each chapter, but no source is given, so they were assumably taken FROM the ebook. despite this, the chapters lack a synopsis. https://tfwiki.net/wiki/Transformers:_All_Spark
this is my first time using LMW, so apologies for any unprofessionality. thanks in advance.
