Supreme trollan’ there, Saki.
This episode has left me with no doubt that Saki has the Geass of Mahjong. And Ikeda kinda reclaimed herself with this episode! Look at that near Kokushi Musou! ‘s too bad Saki trolled her out of winning.
(Yes, in mahjong, the ultimate trolling method is to win with a cheap hand to prevent another opponent with a potentially huge hand to win.)
