Gambling Apocalypse Kaiji manga volume 4 features story and art by Nobuyuki Fukumoto.

A rare survivor of the Human Horse Race, Kaiji is invited to join another deathmatch…This game is called E-Card!

Having survived the games at the Starside Hotel, Kaiji is invited to join another game for a chance at even more cash! But while the previous game was physically challenging, this game, E-Card, is socially twisted. At its core, it is a card game similar to rock-paper-scissors, but as the cards played - slave, citizen, emperor - the power balance is not in the favor of the challenger.
