Touhai Densetsu Akagi: Yami ni Maiorita Tensai

Synopsis

Ichikawa now goes on the offensive by targeting Akagi directly, proposing a Zetsu Nimon—the two discard pin and sou tiles. Akagi loses the round but avoids losing the match. In the following round, even with a poor start hand Akagi confuses the opponents by discarding unexpected tiles, making them believe he has a good hand. Uncertain if it is a bluff or not, Ichikawa gives up the win to another player by playing into his hand, thereby robbing Akagi of his chance to win. After consecutive wins, Akagi establish his own points but cannot take away Ichikawa's points. Seeing an endless match, Akagi offers to cut their points down to one tenth—Akagi has 5,000 and Ichikawa has 10,000—, which Ichikawa refuses. Then, Akagi cheats as to force Ichikawa to accept.
