大宮　エツ子

By the time the match with Reiko is over, she has nearly drunken herself into a stupor. She says her friend who wanted to keep the first printing of leaflets is a nurse named Etsuko Oomiya. Killing two birds with one stone, the party hauls Reiko off to the hospital, where they are fortunate that Etsuko is on duty. It's the night shift by this time, so she can spare a few minutes to answer questions. She confirms that she gave the first, flawed printing of leaflets to her friend Fukiko, but is tight-lipped about what Fukiko's last name is or where she can be found until bested in a strip mahjong game.
