What is the Super Dragon Ball Heroes manga?
Super Dragon Ball Heroes, the manga, consists of two ongoing serializations in Shueisha's bimonthly Saikyō Jump, both written and drawn by Yoshitaka Nagayama. Both adapt story lines original to the Super Dragon Ball Heroes arcade game. The first series, subtitled Dark Demon Realm Mission!, adapts story lines including the arcade game's "Dark Demon Realm Invasion arc" (DBH), "Dark Empire arc" (SDBH), and "Dark King Mechickaboola arc" (SDBH, ongoing), with some elements drawn from the story mode of the Ultimate Mission X 3DS port. It covers the exploits of the Time Patrol, consisting of alternate versions of core Dragon Ball characters, in their battle against the time-and-space altering Dark Demon Realm. It initially ran for ten issues (eleven chapters with an extra chapter in its second collected volume), before being replaced in serialization by Universe Mission. Dark Demon Realm Mission! returned one year later in the May 2019 issue of Saikyō Jump, beginning the two series' simultaneous publication.
Universe Mission adapts story lines focusing on versions of characters closer to their core series, Dragon Ball Super counterparts, which currently covers the "Prison Planet arc" and its direct sequel, the "Universal Conflict arc." These story lines are also adapted into the Super Dragon Ball Heroes promotional anime.
Both series are currently unreleased outside of Japan.
Doesn't Toyotarō draw the Dragon Ball Heroes manga?
Dragon Ball Super manga artist Toyotarō authored a Dragon Ball Heroes series titled Victory Mission in Shueisha's V-Jump magazine from September 2012 to December 2014. The two series feature substantially different takes on the Dragon Ball Heroes world, and share no continuity with one another. You can learn more about Victory Mission by visiting its page on Kanzenshuu, here, or listening to Kanzenshuu podcast episode #0471. (For transparency, I am a guest on it, but I don't know of any other comprehensive postmortems.)

To kick things off/get at the impetus for making this thread, here are two recent translations/details from the first collected volume of Super Dragon Ball Heroes: Universe Mission, released earlier this week in Japan:
Yoshitaka Nagayama's Universe Mission Vol. 1 self-introductory blurb:
In the back of the volume, Nagayama also dedicates two pages to special thanks in comic-book format. The special thanks are as follows:

Anyway, have at. Feel free to post general reactions to the series, ask questions about things like differences between its version of events and the game's/promotional anime's (several knowledgeable members can probably answer a number of these off the top of their heads), discuss Nagayama as an author/artist, comment on oddities like Putine's bust size being reduced between the original serialization and collected books (yes, really; this series is not a paragon of good taste), etc.
