Born on November 20, 1970 in
Kasuga, Aichi, Satoshi Shiki seemingly knew that manga was what he wanted to do early on, as after graduating from Kyoei Private High he moved straight to Tokyo with some friends to make doujin manga. He would then make his professional debut in the August 1991 issue of Kadokawa Shoten's Comic GENKi magazine, a supplemental to Newtype Magazine, with the one-shot
Tsumi to Batsu/
Crime & Punishment, & over time Satoshi Shiki would find notoriety in the manga industry for his distinctive character design style & general versatility. While he created created original manga like
Kami-Kaze &
XBlade, more recently he's known for manga adaptations of other works, namely
Persona×Detective Naoto (a non-canon sequel to
Persona 4),
Attack on Titan: Before the Fall (based on Ryu Suzukaze's light novel prequel of the hit manga),
The Legend of Dororo & Hyakkimaru (a remake of Osamu Tezuka's iconic work from the 60s, which Shiki only recently finished up), & currently
Casshan R (based on Tatsunoko's iconic cyborg superhero from 70s). Shiki has also provided artwork & character designs for titles like the
Louie the Rune Soldier (
the very first book, at least, before being replaced by Mamoru Yokota) & Sega's online TCG
Sangokushi Taisen, while his art style was
the visual identity for the tabletop RPG series
Shadowrun throughout the 90s in Japan, even being used for the cover of the
1996 Mega-CD adaptation developed by Compile, which wound up being the final Sega/Mega-CD game ever officially released.
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!
