Sword of the Silver Crystal

The Sword of the Silver Crystal (also called the Holy Sword) was a magical sword found by the Sailor Senshi on the moon. It is an artefact from the Silver Millennium and its purpose was to protect Princess Serenity. After Prince Endymion was killed by Queen Beryl, Princess Serenity committed suicide by stabbing herself with the sword out of grief. To avenge their deaths, Sailor Venus took the sword and killed Queen Beryl.

In the present, Sailor Venus kills Queen Beryl with the sword once again. After this, strange writing appeared on the sword which only Sailor Venus could read. This happened to be the method to seal away Queen Metallia. However, out of confusion, Sailor Moon killed Tuxedo Mask (whose body was taken over by Queen Metallia) and then killed herself. However, this didn't really kill them and only freed Queen Metaria from Tuxedo Mask's body.

Afterwards, in an attempt to seal away Queen Metallia and to try to find Sailor Moon and Tuxedo Mask afterwards, the rest of the Senshi threw away their transformation pens and Sailor Venus called upon the sword once again to give her and the rest of the Sailor Senshi more power. Unfortunately, this plan failed and left them powerless.

The sword is also used in Sailor Venus' Venus Wink Chain Sword attack.
