The Outer Guardians insist that the only way to retrieve Chibiusa’s soul while preventing Sailor Saturn’s awakening is by killing Hotaru, and depart to do so. Mamoru stays behind to keep Chibiusa alive with his powers while Usagi and the others also leave to the Mugenzu area, where Mistress 9 rejoins Master Pharaoh 90 and orders Kaolinite to get rid of the Sailor Guardians. When Usagi and her friends storm the Mugen Academy building, they are attacked by the Witches 5, revived by Kaolinite, which end up destroyed by the Outer Guardians who come to their aid. Once reunited, the eight Sailor Guardians decide to fight together and confront Kaolinite, who transforms into a Daimon but is destroyed by Usagi. Meanwhile, Hotaru’s spirit inside Mistress 9 watches powerless as she swallows Chibiusa’s Legendary Silver Crystal.
