Itsuki Minami, known as Ikki by his friends, got in a fight with a Storm Rider group called the Skull Saders, and lost. At that point he gets more and more involved with the world of Air Gear and discovers a secret that the Noyamano sisters kept from him. He then decides to try out a pair of Air Trecks from his sister and ends up at an Air Treck meeting challenging the Skull Saders team by accident. This due to the attractiveness of Simca Simca on Ikki.

The silent battle between Akagi and Yagi ensues and nothing else matters except whose judgement in their own actions wavers first. Yagi knows that he cannot beat Akagi fair so he uses a form of cheating called the "caterpillar" in order to utilize the genius Akagi's weakness. As soon as Akagi learns this fatal mistake he decides to counter by taking them for all they've got.

It hasn't been long since Akagi's legendary victory in his first game of Mahjong and Yasuoka has already set up a match for him, in 3 days from now but Akagi wants more from him. He is called in by the gang he's supposed to play against and they want to make a deal but whilst there Akagi meets a mysterious blind man who will later be his opponent.

It is the date for the rematch between Akagi and the Kawada group and now with the stakes so high, they decide to go with the blind Mahjong master Ichikawa as Akagi's opponent. The only problem is that Akagi hasn't arrived, so Nangou is forced to take his place. Akagi makes it just in time but he has a lot of points to cover if he's going to win this. Let the Tse Ii Men begin!

The match has turned into a one-on-one "Tse Ii Men" between Akagi and Ichikawa and due to Ichikawa's effective strategy; Akagi is beginning to feel the pressure. However just when Akagi is at near with only 5,000 points, he's surprisingly able to make a comeback. Nonetheless with Ichikawa playing defensively there seems to be no end to this game, so Akagi decides to win even through more dirty methods.

Following the dirty stunt Akagi pulled, the game of Mahjong has turned into a sudden death with players left with only 10% of the points. With Ichikawa now using any means to achieve victory, Akagi must now turn the match in his favour but whose side will luck be on tonight?
