Before all of that, though, Satoshi Shiki first truly made his name with a manga that has a little bit of an interesting publication history to it, (originally) simply titled Riot.
Debuting in the supplemental issue of Comic GENKi that came with the November 1992 issue of Newtype, Riot would be serialized in both Comic GENKi & Newtype (mostly the former, but one or two chapters in the latter) before coming to an end in the May 1994 issue of Comic GENKi, five months before the magazine itself would end & be replaced with Comic Newtype in 1995, totaling two volumes. Despite the short length it still received some promotion & notoriety, most notably a "Kadokawa CD & Book" titled Riot: Yuuhi ni Ochiruboshi/The Star That Fell Into the Sunset that came out in October of 1994, around the same time Volume 2 saw release, & from what I can tell was an original story that could be experienced either via reading the included book or by listening to the included drama CD; Nobutoshi Canna (then Hayashi) & Akemi Okamura voiced the two main characters in it. There was also a Riot Image Album around the same time, which was really more of a collection of pre-existing songs by J-Rock band Brain Drive (plus one song each from M-Age & The Mad Capsule Markets), though Kaoru Wada (InuYasha, Ninja Scroll) was also involved in it, my guess being for the two in-character monologue tracks featuring Canna & Okamura. Someone actually uploaded the album over on NicoNico Douga, minus the monologues, & it's enjoyably 90s electronic rock & (sort of) industrial metal. However, Riot itself was never properly finished, instead merely stopping during a lull in the story. It looks to be that Shiki simply became preoccupied with other work during Riot's serialization, namely his stuff with Shadowrun & also doing work for Metal Hazard Mugen (a planned anime that wound up never making it past pre-production), & his next manga serialization wouldn't be until 1997 with Kami-Kaze for Kodansha's Monthly Afternoon magazine, which would run until 2003. While making Kami-Kaze, though, Shiki would decide to return to Riot in 1998, this time working with Shueisha to not only re-release the initial two volumes, now under the title Riot of the World, but also serialize new chapters that appeared in Ultra Jump magazine.
However, this revival was rather short lived, running between Issue #23 of 1998 & Issue #29 of 1999, with only one more volume of content getting made before the manga would go on hiatus for a second time, once again leaving the series unfinished to this very day. However, Satoshi Shiki actually did say in a random response to a quote tweet I made when he shared old artwork of it in 2018 that he would love to return to Riot of the World again one day. I should also note that there is a book out there titled Riot Versus the World that looks to have come out in mid-2001, after Volume 3 of Riot of the World's January 2000 release, but from what I can tell it was a self-published doujin by Shiki & his staff at Wrench Studio, so I have no idea what's actually in the book or if it's even a continuation of the story in any way; it could very be like Bastard!!: Unused・Revised Edition & contain exclusive bits of plot, for all I know. It is worth noting, though, that both the "Riot of the World" & "Versus the World" nomenclature first appeared in that 1994 Riot Image Album I mentioned as song titles, specifically the first monologue & last song; I just think that's neat. Anyway, prior to the manga's return as Riot of the World in 1998 Shiki's original two volumes of Riot saw release internationally, which included an English release by Viz, first via 13 "floppies" (traditional comic issue style, which was still considered the standard at the time) & then later re-released as two proper volumes. From what I can tell this was one of the last manga that had the late James D. Hudnall work on it from a translation adaptation perspective, which is notable as Hudnall was the man Viz had hired to adapt two of its very first releases back in 1987, Area 88 & Mai the Psychic Girl; Hudnall would later also do some lettering work for Viz, but adaptation work seemed to stop after the late 90s. Unfortunately, by the time that third volume of Riot of the World came out in Japan in early 2000 Viz was seemingly no longer interested in putting out more Riot in English, as they had "fully" released all of it by mid-1997. A similar thing would later happen with Beet the Vandel Buster, i.e. more came out long after Viz had "finished" it, so Riot's at least in good company.
When I was first really getting into manga in the mid-00s, after having become an anime fan, I was lucky that some of these flipped trade paperbacks of the 90s were still relatively cheap (they've now generally become more valued with time), so Riot was one of those manga that I read early on in my time as a manga reader & I remember really enjoying it, despite its unfinished nature. Does that remain true for me 20 or so years later? Was that third volume really worth the wait? Is there any reason to go back to Riot & hope that Satoshi Shiki might one day bring it back again? Only one way to find out!
