Sailor Neptune (Kaioh Michiru)


Warrior of the planet of the sea, Neptune is certainly the most elegant of the Sailor Senshi. Although she is a water warrior like Mercury, Neptune is of the sea and has no ice attacks like her counterpart.

Michiru is portrayed as a very polite, calm character in the series. She dislikes being patronized even if not doing so would hurt her feelings and subsequently will not indulge people. This is alluded to in her back story, explaining that she was congenial but generally not social. Michiru is also graceful and delicate with an aura of sophistication. She is capable of sharp anger and often comes off as being or acting cold. She is clearly intelligent, and this usually manifests itself through art and music (femininity and music are emphasized in her character design).

Michiru's closest bond is with Haruka, and Takeuchi has explicitly stated that the two are in a lesbian relationship in both the manga and anime as well as the musicals. Michiru and Haruka are very similar in some ways, such as their notoriety and sense of duty. Just as Michiru has her similarities with her love, Haruka, she also has her differences. Haruka has an air of masculinity while Michiru is extremely effeminate; she is very much a woman, not necessarily in a stereotypical way but in that she is very elegant and refined. She is usually seen in flowing skirts and dresses, and her lipstick is noted on a couple of different occasions. Her talisman is a hand mirror, which she often uses

Michiru attends Infinity Academy with Haruka (and the younger Hotaru Tomoe) when she is first introduced. In the manga, after Infinity is destroyed, she and Haruka later attend the same high school as Usagi and the other girls. It is never mentioned where they go after this in the anime. According to the musicals, Michiru had experience studying abroad.
