Show your fingers to a giant to show you refuse him. Giants are very big. So big that when you talk they can't really hear what you're saying. Hold up all your fingers so that he can see what you mean.
What do you refuse? You refuse to let him stomp all over Little Kyoto (きょ). Little Kyoto is your home! And if the giant comes any closer he's going to destroy all the little buildings and shrines and soba noodle shops.
