That’s right, the winner of the contest is Yukio Hirayama, aka “Fake Akagi”, one of the victims of Iwao Washizu.
In the manga and TV anime, Hirayama perishes after losing all of his blood to Washizu in a game of mahjong, but pixiv Zingaro is happy to report that they were able to revive poor Hirayama with 9200 millileters (19.4 pints) of donated blood.
