Mistress 9 is a malevolent entity from the Tau Ceti Star System sent to Earth with one goal: opening a gateway for her master, Pharaoh 90. She's known as the "Messiah of Silence" and has possessed Hotaru Tomoe's body—though the degree of control she exerts over the girl shifts throughout the story. Fans often debate how much of Hotaru remains present during Mistress 9's possession, especially as events unfold and her true nature becomes clearer.
