Iwao Washizu

Washizu has long, slicked-back white hair and a long crooked nose. He is typically seen with a toothy smirk. He wears a black long blazer and a low-cut vest with four links holding it shut, flowers on the ends of each. In the manga, Washizu can be seen wearing a bright red top with a tall mandarin collar, trimmed and embroidered with golden yellow. In the anime, the shirt's red and the vest's black are swapped. According to Washizu: Lord of Mahjong Hell, in his younger years he was a muscular man with wild black hair and a manic smile. He usually wore a loose white dress shirt and a black or dark brown suit jacket with matching pants and slick black leather shoes. In the earlier chapters of the spinoff, before he begins to gain traction in his plan for an underground empire, he always carried a duffel bag of sorts with him. In his older years, Washizu is an obsessive and confident, almost cocky man who uses large sums of money to tempt younger people into betting their lives in mahjong games. He invented a new variation of mahjong which he named after himself - Washizu Mahjong. He enjoys playing these games greatly, and the bets throughout the games are counted in blood. Washizu finds joy and amusement in watching the suffering of others, which is why he plays this version - the victim slowly loses their blood, resulting in a slow and dreadful end. After building up massive funds from shady dealings in Japan's post-war era. He enjoys doing this, so a match between Akagi and Washizu was arranged. Washizu Mahjong is a version of normal mahjong in which some of the pieces are made of glass - they are transparent. This adds an extra layer of psychological work and analysis, and makes the game much more difficult and interesting to play.
