Sailor Neptune, Michiru, was introduced in Sailormoon S with Sailor Uranus. The two are very close (yes, they are in love, but that's not what I mean), and have a wonderful partnership. They'd never admit it to each other, constantly saying that they would each sacrifice the other, but they never would allow the other to die. Sailor Neptune demonstrates this many times, putting herself in horrible danger for Uranus. She can play the violin very well and is very reserved and graceful.
