Iwao Washizu Husbando

An old man who had made a lot of money after building up massive funds from shady dealings in Japan's post-war era and one of the most powerful people in the underground. Washizu is an obsessive and confident, almost cocky old 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.
