Week 7 Reading A: Japanese Mythology

The story of The Miraculous Mirror is kind of confusing to me. I don't understand why Amaterasu would run away from her brother Susa-no-wo. Even if he's evil and was there to harm her in some way, it seems like she would be able to take care of the situation. She's literally the queen of heaven, so shouldn't she be more powerful than her brother, not to mention have body guards or an army to protect her. I also don't understand how she could be tricked into thinking her reflection was a rival and coming out of her cave to fight it. Again, she's the queen of heaven, not a dog who doesn't understand how mirrors work.
