Crazy that Izumi called her employee at the meat shop and said something to the effect of, "Hey, I know I'm only giving you a couple hours notice but I've got two kids that I'm going to ditch in Yock Island for a month to test them, could you hide there and watch over them covertly to make sure they don't die. I'll pay you extra if you also put on a komainu mask and terrorize the shit out of them." And then Mason, the otherwise completely normal butcher's assistant, was like, "How did you know this was my life's dream," and went off to live in the wilderness and attack children for thirty days and nights.
