I really enjoyed this volume.
Some events were different than what happened in the anime and I like the change, it'd be cool if these fights happening in the manga could be animated because I'd for sure watch that. I mean I am a big rwby fan, been watching it since the trailers came out, and now I pick up the books and manga because I just love rwby as a whole. Though there are a lot of things i don't like about the anime, and things that could've been done better, overall I love the anime, and that made me pick up the mangas.
Anyways the fight in this volume between Sun, Neptune and Roman in the giant robot suit, I wish that happened in the anime. I mean it sort of did, just not the way it happened. I really liked the way the scene was illustrated and done. Like you could actually see the characters scrapes and such, they don't really show things like that in the anime until like volume or season 4-5. The only time i can really see someone getting slightly hurt is with Weiss in the white trailer, and Yang in volume 3 but that's a whole different case.
Though this scene in the manga I really enjoyed, the Mangaka gave Sun and Neptune more fighting or screen time, I liked that they could both show of their moves equally because that doesn't happen in that fight scene in the anime. I remember Roman was chasing them on a highway and Sun was fighting him with Blake. Neptune didn't really do much in that scene, and once sun get pushed away with Neptune, they didn't come back up. They did but like later at some restaurant. It was funny in the anime. I like how serious the manga is compared to the start of the anime. I really liked their teamwork because the only other time in the anime we see them working together is in the Vytal Festival, and I love these guys they're fun and cool.
Anyways those are my thoughts, lots of spoilers if you haven't seen the anime. My bad I was just getting really into it.
