It's true. Miro became the sacrifice of humanity to create a barrier to prevent Arcangels from attacking earth. And she's the disciple of Shirone's father. In the surface, Miro was known as an Arcmage that created her own world and become a g**/demigod but the truth is she's protecting the world from being annihilated. As for the invasion, that never happened. After Shirone and his friends escaped heaven for the first time, Shirone has his training arc to save Miro with Miro's old classmates. They went back to heaven and destroyed it. Tho later on, there are some entities that's trying to invade their world. Iirc, it's not Ra but different gods or spirits. Valkyrie even exist. Unfortunately, Valkyries seem to be an enemy.
