A genius that fell into darkness. The god of the underworld.
Akagi runs from a chicken fight where he almost died to a Mahjong place, where a man loses all his money to the yakuza. Akagi who is only 13 tells him that he plays it wrong, although he has never played the game before. Akagi replaces him in the game, and so a legend is born.
When the police comes to check on the place to see if the kid that ran from the chicken fight is there they deny the relation of Akagi to the chicken fight. In the end the policeman invites Akagi to a much more organized Mahjong game and from there the legends only continues to enlarge.
