Cosmic Heart Compact

Cosmic Heart Compact is the third device that Usagi Tsukino uses to transform into more powerful Sailor Moon.

Characteristics
The Cosmic Heart Compact was given by Neo-Queen Serenity to Usagi in order for her to transform into a much stronger and more evolved version of her standard Sailor form.

It still contained the Silver Crystal inside just like her previous transformation device the Crystal Star did.

The Cosmic Heart Compact replaced the Crystal Star in act Act 26 when it was destroyed after the battle with Death Phantom. The compact first used in Act 27 when Usagi needed to transform when a Daimon appeared. The Cosmic Heart Compact has protected Usagi in her civilian form. For example from Cyprine brainwashing and it also created a floating barrier when the newly awakened Mistress 9 attacked Usagi.
