Prequel manga to ''{{Akagi}}''. In 1945 post-war Tokyo is a city of ruin to Washizu Iwao, a man returning to Japan after mysteriously leaving the country and the police force in the middle of the Second World War, and he has taken it upon himself to reshape it in his image. Founding the financial consultation firm 'Kyousei' three years later, he begins a fierce crusade to take over Japan from the shadows using his greatest asset: his skill at mahjong. That, and the healthy dose of coersion, brute force and blackmail, of course.

What follows is a surprisingly good and downright bizarre spin-off manga about Washizu's sociopathic exploits with his trusty underlings, Hayabusa and his Secretary, as they battle the stock market, pirates, yakuza and everything in between in the seventeen years before the start of Akagi. The series was neither written nor illustrated by Fukumoto, who is instead credited as an assistant.

!!'''This manga provides examples of:'''

* AcePilot: Ostensibly Hayabusa, a kamikaze pilot who miraculously survived the War. [[spoiler: Turns out to be a subversion; the only reason he survived is that he faked his own death and deserted while he had the chance.]]
* AnOfferYouCantRefuse: Generally how Washizu comes into ownership of up-and-coming companies.
* {{Badass}}: The 'entire series'. At one point Washizu is encased in concrete and still manages to maim and kill several people. ''Without'' being broken out first.
** [[TwoWordsObviousTrope Two words: Washizu Copter.]]
* BitchInSheepsClothing: [[spoiler: Koshiba, one of Kyousei's newest workers. He does an excellent job of pretending to be a klutzy intern while secretly plotting Washizu's downfall.]]
* BlackComedy
* ButForMeItWasTuesday: Washizu's reaction to the big reveal of [[spoiler: Koshiba's]] true identity: "Who?"
* CorruptCorporateExecutive: All of Kyousei.
* DisproportionateRetribution: Washizu does this a lot.
** What's the correct way to deal with the man you just beat at mahjong? [[spoiler:[[EyeScream Ram mahjong tiles into his eyes]], of course!]]
** In response to being called a cheater by a top baseball player, Washizu buys himself a baseball team and masters the sport ''just'' so that he can beat the guy at his own game and get him to admit he was wrong.
* DitzyGenius: Hayabusa, to some extent. He's supposedly almost as insightful as Washizu, but this tends to get lost while he jumps to conclusions and shows off his questionable reading skills; he has a thing for comic books and often misreads kanji, the latter being somewhat of a running gag.
* Expy: The Secretary is visually a reference to Taizo of ''{{TheLegendOfKoizumi}}'', and earlier volumes of the manga are very similar in tone.
* FanDisservice: Washizu working out. In a ''fundoshi''.
** Also Washizu eating a live lizard.
* FanService: Of the non-sexual kind; a younger Yasuoka from ''Akagi'' makes a cameo appearance in one story as a street cop.
* FiveManBand:
** TheHero: Washizu, though he's more of the SociopathicHero variety.
** TheLancer: Hayabusa. Interestingly this role should technically go to the Secretary, who is the second-in-command at Kyousei, but Hayabusa spends more time with Washizu and is generally a better fit.
** TheSmartGuy: The Literary Man. He was educated at Kyoto university and has a PhotographicMemory.
** TheChick: The Secretary spends most of his time [[JamesBondage getting kidnapped]] or hovering anxiously in the background while Hayabusa and Washizu do all the work.
*** Hilariously Lampshaded by the Secretary himself, who laments that he gets stuck with all the paperwork while Washizu and Hayabusa galavant off having adventures.
* FountainOfYouth: Washizu comes up against a man who claims to have created a formula that ages and de-ages humans.
* LargeHam: Washizu himself.
* ''{{Mahjong}}''
* TheMole: [[spoiler: Koshiba.]]
* TheReveal: Hayabusa's real name is [[spoiler: Suzuki, making him Washizu's right-hand man in ''Akagi''.]]
* NoNameGiven: Frequent. The Secretary, the Literary Man and the pirates are only known by their titles.
** The Secretary is an interesting example, given that his name reflects his position in the company- at the start he's simply a secretary and is referred to as such until Kyousei expands and he becomes the Head Manager, getting a name change to match his promotion.
* {{Pirate}}: Volumes three and four can largely be summarised as Washizu vs Pirates.
* RatedMForManly: Unbelievably so, for a series about Washizu Iwao.
* RuleOfCool
* VillainProtagonist: Washizu, of course, but most of Kyousei also qualifies; the Secretary happily strangles a boy with a car window and Hayabusa is all for blackmail.
