October 12th: Stormy Drying Agent - S1.E7

A typhoon hits during the say of the Sports Festival and has to be called off until the next day when the typhoon has already blown over. Later on, Yuno and her friends are in Miyako's room worried that if the drying agents under her floor get wet they will ignite and catch the building on fire. Miyako gets the idea to remove them all, and throws one into the rain outside, but it does not catch fire.
