the story mainly recovers the trailers with added detail, the site I read the manga at actually has 15 chapters, and chapters 10-15 are the only chapters that add to the story. with that said I very much enjoyed the added detail into the trailer recap, as well as the extra story the manga add, while I may be bias since I'm quiet a RWBY fan I'm giving the story 8 (I'd also suggest reading the chapter MAL doesn't list). the art was pretty good and I enjoyed seeing characters I had only seen as 3D models in a 2D Anime/Manga art style so again an 8. the characters where pretty accurately portrayed and further developed so I'll give them a 8. finally I very much enjoyed this manga so I'll give it a 10 leading to an overall 9. If you're a RWBY fan you'll most likely enjoy this manga, if you're not I'd suggest watching the first 2 volumes before picking this manga up.
