Sailor Neptune appears at the beginning of the S season along with Sailor Uranus. The two of them are, well, you know... Anyways, she possesses the Deep Aqua Mirror, which is the second Talisman (Uranus's Space Sword is the first). Sailor Neptune has a lot in common with Sailor Mercury. Besides the fact that both of them use water-elemental attacks, they each will use intellectual deduction to resolve troublesome situations. Her partner (Sailor Uranus) on the other hand, will jump right into the action before thinking things out first. Michiru has a very cool, calm, and collective personality, which seems to be a theme among water-wielding Sailor Scouts. Like Sailor Uranus, Sailor Neptune takes her missions very seriously and would not hesitate to sacrifice herself for the cause. Often she will intentionally put herself in harm's way to save her partner. Both Sailor Neptune and Sailor Uranus seem to be more mature than any of the other Sailor Scouts. Don't expect any doofiness out of either of them.
