The Summer of 1965 is the date that marks the beginning. A young man's buried corpse was discovered in the Tama Mountains, with his death caused by shocked induced blood loss. The body is later identified by Yasuoka as Yukio Hirayama (Fake Akagi) and Yasuoka already has a thought lingering in his mind and decides to search for Akagi with his acquaintance Ohgi. At the same time, Akagi is at the Kurata group gambling house and he seems to have gotten himself in trouble.

After saving Akagi from a meaningless death, Yasuoka and Ohgi want to put him up against monster whose been causing the recent string of mysterious deaths, in a high stakes game. The monster that he will go up against is Iwao Washizu and his background is revealed. After spending two weeks with the Inaba group Akagi finally receives the call for the match worth 20 million but there seems to be some frightening house rules put in place.

The gruesome Mahjong game between Iwao Washizu and Akagi is about to begin and with all the house rules put in place this could easily become a death match. However Akagi is not satisfied with the 20 million wager and request that Iwao increases it, tenfold. But it will take a lot to convince Iwao.

The game of Washizu Mahjong has begun, where Akagi wagers 2,000cc of his own blood and Iwao Washizu wagers of his entire 500 million fortune. Akagi starts of by playing defensively to gain points but he soon learns that this tactic won't work in Washizu Mahjong. The harsh reality of this game, surfaces.

The Washizu Mahjong death match between between Akagi and Iwao continues and Akagi managed to gain some ground with his "Tan Yao Dora 1". But Akagi is still in danger unless he outranks Iawao, by the Han Chan session. He must find a way to outwit Iwao before his luck runs out.

After patiently waiting for an opportunity to arise, Iwao lets down his guard giving Akagi a chance to strike by calling a Tong, Chun, 1 Man and is looks to be in Ten Pai but will this bluff pass? Onto the 2nd sessions and Akagi goes into it without transfusing the 600cc of blood back into his body. What could he possibly be thinking?

Well into the 2nd session Akagi causes a massive upset to Iwao and has a chance to transfuse his lost blood but yet again he refuses, just to focus on taking Iwao's money. Nonetheless Akagi picks up the momentum and begins to dominate this session but when it comes to the final round, there's a single tile that proves to be a major obstacle.

The 2nd session of Washizu Mahjong reaches its climax, as Suzuki receives the decisive "Xia" tile and everyone foresees Akagi's demise, except Akagi himself. Akagi eventually manages to deal his Xia tile and go into "Ten Pai". Even so Akagi knows that he is at a great disadvantage because he's on a single wait for a "1 Man"; on the other hand Iwao has a large number of possibilities in getting a "Hane Man" to overtake Akagi.

The 2nd session is over with Akagi's victory by baiting Iwao into dealing his winning tile allowing Akagi to "head bump". Akagi then explains the long process to Yasuoka and Ohgi, of how he managed to win in such a disadvantaged situation. Due the prior conditions, Iwao has a chance to back out of the match but will he take it?

The 3rd session has begun after Iwao Washizu chose to continue; Akagi has lost 1,000cc of blood and Iwao has lost 118.5 million of his fortune. Luck seems to be on Akagi's side, as he constantly gets favourable hands but this may not last long because Iwao seems to have natural born luck.

Well into the 3rd session of Washizu Mahjong, Akagi seems to be near certain death yet again with Iwao Washizu being one draw away from a Tsumo "Hane Man" win. But Akagi's calmness in the face of death proves nerve-whacking to him and even with his hand evolving to a potential "Bai Man", Akagi doesn't even flinch.

Washizu Mahjong continues well into its 3rd session and Iwao Washizu is overflowing with such luck that allowed him to achieve the unbelievable Dora 12, to win by a dealer "Yaku Man" if only he draws the "1 Pin". It's as if he is possessed by something truly evil, yet Akagi still doesn't flinch in the face of death and gets a chance to make his comeback.

Akagi's game of Washizu Mahong continues and having read the very thought process of Iwao Washizu, Akagi is able to capitalize on that by winning the next two sessions. Having lost a total of 1,400cc but gained a total of 313.5 million of Iwao's fortune, Akagi makes a compromise to continue this legendary match where the two wager their death and ruin.
