Sailor Moon was willing to accept the attack first, was glad the attention wasn't on Rei and Venus, honestly. But she was used to facing strong foes, even something as strong as a Valkyrie. She summoned her Tiare and wordlessly summoned up a barrier of light, flying up and out of the attack.

She was not new to battle.

But she also didn't want to hurt Lenneth, not when the actions were fueled pulled by others. That would make her no better than attacking the Amazon Quartet. Besides that, Lenneth was Rei's friend.
