It's time to do the mouth sun sun chant. That's when you use your mouth to chant sun sun, sun sun, sun sun, over and over until the sun appears.

You're doing this chant because the Shougun (しょう) ordered you to. The sun hasn't been shining on him as much lately, and he's displeased. So now you have to chant for him.
