Ep. 36: A Bright Shooting Star! Saturn, and the Messiah

36

Mistress 9 steals the Holy Grail, allowing Pharaoh 90 to pass through the portal from the Tau Star System to Earth. Hotaru expels Mistress Nine from her and finally awakens as Sailor Saturn herself, who had taken possession Hotaru's body and mind, and is ready to obliterate Pharaoh 90 once and for with her immeasurably strong powers of death and destruction, ruin and annihilation.
