A very nice beefy chapter. From the opening discard all the way to Akagi declaring Riichi, that's a sweet amount of progression for one chapter of Akagi, imo. It will never get old seeing Ohgi become flabbergasted by Akagi's decision making. That's one of Akagi's most important character traits, to not do the normal approach, what rational risk averse people do. He always has to do the insane move, the move that makes all those around him shocked and stunned.
Can't wait to see Washizu struggle with his next discard in chapter 173.
