The rainy season's here, and the Defense Club is dedicating themselves to various indoor activities. Suddenly, they realize that Mr. Tawarayama -- whom Wombat is controlling under the pretext of preserving his life -- is covered in mold! The club erupts into chaos. Just then, Kinozaki and Tazawa of the Press Society burst in looking for material for a story. Kinozaki chases them around, trying to learn their secret, which stresses out Wombat, Yufuin, Naruko, and Zaou.
