Definately Uranus. Close second is Neptune, and then either Venus or Jupiter (it fluctuates). But I just think that Haruka and Michiru are so cute together! What about you?
i like Sailor moon herself (that was kind of recent change. i used to like chibimoon) but then theres jupiter, venus, mars and murcury...... I like Edymion and Serenity for pairing.
