Mahjong is a gambling game, it's not meant for recreation really. Also, getting a hand like that as-is let alone at the start of a match is ridiculously unlikely. I've played at least a combined total of like 100+ hours of mahjong over all the Yakuza games and I've only ever done a Thirteen Orphans once while the AI has done some other Yakuman I can't remember to me once.
It would be like you starting with Exodia two games in a row with it in your starting hand.
