I liked Usagi much more in this volume, because she doesn't whine and cry about everything.
(Well, I mean, she is crying sometimes, but at least she has a good reason to cry, and isn't just being a baby about every little thing!) She has some good character development, as she learns to step up and become a true Guardian and a leader.

I loved seeing Tuxedo Masks's storyline taking center stage, and all those mysteries revealed!

I especially like this volume because my favorite character is on the cover, Sailor Mercury! Although, she has very little to do in this volume other than fight alongside the others.
