Sailor Neptune

Her name in Japanese is Kaioh Michiru. In the English dubbed TV series, she is known as Michelle Kaioh. Michiru-san's birthday is March 6, under the zodiac star sign, Pisces the Fish. Sailor Neptune first appeared in Sailor Moon Eternity (manga) and in Sailor Moon Super (anime).

Sailor Neptune isn't a guardian Soldier to Princess Lady Serenity like the Inner Soldiers. Instead, she is a protector of the Solar System to keep invaders from threatening the Silver Millenium along with Sailor Uranus and Pluto.

When she was reborn on Earth, her mission was to defeat the Death Busters, a powerful enemy infiltrating Earth through the time space continuum. As Kaioh Michiru, she was a famous violinist, had a rich apartment on the Triangle Delta surrounding Infinity College, and was an exceptional swimmer.

Being an Outer Soldier, Sailor Neptune bears one of the three talismans used in summoning Sailor Saturn, the soldier of Silence and Destruction. Her talsiman is a mirror. She can see many different things in her mirror, such as visions of impending doom, a comet just entering the solar system, who someone was in their past life or just for criticizing how a new shade of lipstick doesn't suit her.

In Sailor Moon Eternity and Sailor Moon Super, Neptune and Uranus didn't show any interest in working together with Princess Lady Serenity and her guardian Soldiers. They were convinced they would just get in the way. Their goal was to kill Sailor Saturn and make sure the three talismans were never able to summon her. Unfortunately, Sailor Saturn turned out to be sleeping in Hotaru, Chibi-Usa's new friend.
