Touhai Densetsu Akagi: Yami ni Maiorita Tensai

Synopsis

Akagi shows an amazing ability for someone who has never played mahjong before, predicting the opponents' tiles by looking at their discards in order to not discard tiles useful for anyone's hand. Seeing the possibility that they may lose to Akagi, Ryuuzaki, the yakuza leader, calls the clan's best player, Yagi Keiji. After observing Akagi playing, Yagi makes his own bet of 100,000 yen for round, offering a finger for 100,000 yen as he knows Akagi does not have that amount of money. Akagi does not recede, accepting the bet so long Yagi also parlays the same for his fingers. The game restarts but now instead of game of skills, it is a psychological game, wherein Akagi still appears to be winning.
