"VENUS! REI!" Usagi was never one to care about herself above her friends. Her friends were her life. So she quickly moved the barrier from herself to protect Venus and Rei, even if Rei could melt the ice, she didn't want to chance it. She used even more energy of her light to keep them safe, making the barrier as thick as possible while still keeping some for herself.

Which was why, now that her own barrier was weaker for it, while the swords of light were slowed, they still struck their mark and she was hit... hard. Her crystal was quick to start immediately healing the damage but she was slammed back into several tables, chairs, and eventually the wall itself, her weaker body taking nearly the full brunt of the damage.
