Akagi is a pretty fucking stupid show. The show is about a guy who plays Mahjong and uses magic sand to give him an edge. He keeps a small vial of it around his neck and when he starts losing a hand he discreetly pours a little of it on his hand. Then he uses his pinky finger to swirl it around in a gay way and time stops so he can switch his tiles out with ones from the wall.
The way he got the sand was pretty stupid too. In episode 2 he finds an Elf with huge tits in the back of a truck who is connected to some kind of government cover up. He frees her and as thanks she gives him an oil drum filled with the sand.
She said that there was some kind of a downside to using it, but the series ended without getting into it.
