Striking down enemies
The Samael Sword was a sword that was used by some of the villains of the Dracul arc in the Sailor Moon musicals. It was first used by Undead Berserk in "Pretty Soldier Sailor Moon ~ New/Transformation - The Path to Become the Super Warrior - Overture of Last Dracul" when he attacked Sailor Chibi Moon and extracted her Star Seed. In the same musical, Undead Berserk used the sword to perform Samael Jihad in an attempt to seal Sailor Moon away in the underworld, only for Count Dracul to step in and shield her from the attack, thus sealing him away in the underworld instead.
The second and final person to use the sword was Baron Gilles de Rais in "Pretty Soldier Sailor Moon ~ Decisive Battle / Transylvania's Forest - New Appearance! The Warriors Who Protect Chibi Moon -" who used the sword to perform Samael Jihad, which struck the Sailor Senshi down. However, Sailor Astarte reversed the sword's effect with Solomon Birth.
