Their dorm is a biohazard, no wonder their batch of sake turned bad, they're walking contaminators.
It's also amazing how some superstitions are still used as "remedies" for all sorts of things and people are willing to pay huge amount of money for it in today's age of science...
These fools not only are in debt for taking people money for sake they should be making but now getting billed for the damage, time to sell kidneys lol
