Act 7 Mamoru Chiba - Tuxedo Mask -

Positioned as the seventh chapter of the Pretty Soldier Sailor Moon manga and the seventh piece of its Dark Kingdom storyline, this entry is credited to Naoko Takeuchi. The plot confirms for Usagi that Mamoru Chiba and Tuxedo Mask are one and the same and lays out his reasons for chasing the Silver Crystal, all while Zoisite spreads recorded tapes that bend the minds of Tokyo's residents.

Coming to inside Mamoru's apartment, Usagi notices a cape and mask nearby and grasps that he leads the secret life of Tuxedo Mask. He shares how a crash claimed his parents and his memories, leaving him haunted by a dreamed woman who insists the Silver Crystal will restore his past. Despite Luna's earlier warnings, Usagi feels her defenses slip and her affection for him grow. Convinced by Sailor Moon's show of power that she might already hold the gem, the enemy has Beryl channel stolen human energy into reviving Queen Metalia, then blankets the city with video cassettes designed to turn everyday people into searchers hunting Sailor Moon down.

Sailor Moon breaks the tapes' grip on the populace but is soon captured by Zoisite, who walls her off so neither her fellow guardians nor Tuxedo Mask can reach her. Just as he moves to end her life, a newcomer strikes him dead and stands revealed as Sailor V, accompanied by a white cat named Artemis. This marks her first in-the-flesh appearance in the manga, following her debut over in Codename: Sailor V, and it introduces Moon Healing Escalation, Supreme Thunder, the Crescent Boomerang, and Minako's Compact. The act falls between Act 6 Tuxedo Mask and Act 8 Minako - Sailor V, with a matching Sailor Moon Crystal episode adapting it.
