Watanuki gets the day off from the shop, so he spends it reading manga and just lounging around his house. He ignores some old superstitions, saying he doesn't believe in them. For example, if somebody buys new shoes the person shouldn't wear them at night, or if somebody sleeps after eating, the person will become a cow. Watanuki then takes on a superstition about if somebody cuts their nails, the person will not be with their parents during their death. Anyway, next day, he finds that these might be true after all, then he is then saved by Yūko.
