Michiru transforms in front of Haruka and ultimately saves her from a monster. Haruka asks Neptune why she covered her during the attack. Sailor Neptune tells her she didn't do it because she knew Haruka was another soldier . . . she did it because she had been watching and admiring Haruka for a long time.
