When Akagi finally loses 2000 ccs, the fatal amount, he survives, having pumped 500 extra ccs of blood into his body before the match. Eventually Akagi takes his entire fortune, and Washizu begins to bet his own blood. After multiple brushes with death, Washizu eventually dies right before his own victory, and his white suits forfeit the match to transfuse his blood back. Akagi leaves his own cut of the fortune behind, deciding that he didn't defeat Washizu, he only outlived him. 6 years pass, and Akagi is now being followed by Osamu. Frequently winning huge amounts of money in gambles, an exciting venture Osamu, to Akagi's own detriment, who is trying to get Osamu to leave him alone, telling him people like him "start to think they're my friend". When the house comes demanding money back from Akagi, he finds a way to escape with his money. During this time he is being chased by Washizu, who demands a rematch. While he still thinks about Washizu, stopping at Washizugatani Station, seemingly on the simple whim it happens to contain Washizu's name, Akagi shows no interest in a rematch. Akagi, after imagining Washizu in the local bathhouse, tells Osamu he can stop by the bathhouses, and he may even meet "someone you'd never want to meet".
 * -|Mahjong Demon=

During this time in his life, Akagi is obsessed with getting to the essence of gambling, which he has surmised to be "a meaningless death". Due to this obsession, he constantly raises stakes with the main purpose being to force his opponents to put everything on the line, by extension of this goal, Akagi is more than willing to lose his own life to the whims of a gamble. This attitude causes him to be described as insane, or a demon due to the skill that accompanies these death matches, Ohgi surmises what Akagi yearns for is not a worthless death, but an even match that will finally excite him, a goal mostly fulfilled by his match against Washizu. During this time Akagi is friendless, wandering without making many connections, and only seeming irritated by the attachment characters like Osamu have towards him. By the end of this match, Akagi confirms to himself that when he dies he wants to die as himself, the same way Washizu did.
