My First Time at the Bath with Everyone

As a typhoon hits the city, the gang make a bunch of teru teru bozus to ward off the weather, even making a big one. During the eye of the storm, they decide go to a public bath house, along with Mika, it being her first time. Despite occassional harrassment from Haruka, Kana and Mika enjoy their stay. However, by the end, the eye has passed and they end up being shut in.
