star locket (sailor moon)

An item only seen in the 90s version of Bishoujo Senshi Sailor Moon. A star-shaped locket that Chiba Mamoru first owns, then gives to Tsukino Usagi. Originally, Princess Serenity gave it to Prince Endymion during the Silver Millennium 1000 years ago. It plays a lullaby version of Moonlight Densetsu, and helps Sailor Moon purify Mamoru from his corruption by Queen Beryl.
