The school's swim team is preparing for the test, and the teacher tries to cheer them up by encouraging them to swim. He tells them to prepare an umbrella so that they don't have to worry about getting wet in the rain. He also tells them that they should prepare their bodies for the swim test by drenching them with a mixture of water and fenrir. The teacher then tells them not to get too close to him, as he will show them the way to swim
