While Kaiji ponders himself on the decision, he is visited by Miyoshi and Maeda, two of his 'allies' he had saved from the last part of the series.

Side Story

manga
Ootsuki, the foreman of the underground debt-slave labor camp, is finally using his one-day vacation above ground. The blacksuits of the Teiai Corporation follow him to make sure he doesn't escape, but are constantly baffled by the completely mundane ways he decides to use his time.

Spin-off

manga
Ichijou Seiya is a young prodigy who is the manager of the Teiai underground casino and the creator of the diabolical pachinko machine "The Bog." Before his fight to the death with his nemesis, Itou Kaiji, he had a youthful period when he was still smoldering and unable to make anything of himself. The story is set in Ooyama, Itabashi, Tokyo, a "bog" that has swallowed up the dreams, hopes, and despairs of young people, and is about the ambitions and difficulties of freelancer Ichijou and his younger colleague Murakami who move into the capital and live in a tiny apartment.
