Haruka Misono (御園 ハルカ Misono Haruka) is the President of Tokorozawa and Chiaya's adopted mother. Much like Chiaya, she is also an alien, but from a different species. She is gathering heart stones so that when the time comes, she can return Chiaya home to her real family. She is overprotective of Chiaya keeping her confined to her home with Momiyama, worried that she would get in trouble if she had revealed her true form to others. Her true form is a squid-like alien.
