Act 34 Infinity 8 "Infinite Labyrinth" 1

The guardians assemble at Mugen Academy and press into the Infinite Labyrinth, facing its dangers to reach the enemy. Inside, Mistress 9 moves to seize ever more power for Pharaoh 90.

At the hospital, doctors tell Usagi, Mamoru, and the rest that Chibiusa's heart has stopped. The Outer Guardians reason that because the talismans stayed quiet, the being now wearing Hotaru's body is not Sailor Saturn but a Death Buster, one that also stole Chibiusa's soul and the Silver Crystal. They insist that destroying Hotaru is the only way to save both the girl and the world, over Usagi's protests. To keep Chibiusa alive, Mamoru forms a link to feed her his own energy while the others set out to confront the enemy.

Mistress 9, the reborn Daimon inhabiting Hotaru, has become Pharaoh 90's partner and orders Kaolinite to wipe out the guardians while she presents the Silver Crystal to her master. Kaolinite's magic revives the Witches 5, and each Inner Guardian is captured by one of them. The Outer Guardians break through, destroy the Witches 5, and free their comrades. Uniting their power once more, they raise Sailor Moon to Super Sailor Moon and push toward the principal's office, where Kaolinite morphs into a Daimon and is destroyed. Sensing eight guardians drawing near, Mistress 9 swallows the Silver Crystal to gain strength, snuffing out what remains of Hotaru's awareness.

The chapter introduces the Chronos Typhoon and Submarine Reflection attacks.
