Harmless Sparrow is asking for help and I can feel in her voice her desperation. Her desperation to escape and be free on her own decisions. I am not well knowledgeable about her guildmates in Blue Sky but if we are talking about the vice president of the guild then it is another story.
So why can't Harmless Sparrow escape the guild by herself? It was because she is not the one who controls it. She might be the president but the one who freely controls the guild is the Vice President. What if she leaves the guild? She can do that but from the looks of it, the guy must have used something to prevent Harmless Sparrow from leaving, like some blackmail material.
