Now that introduction got me curious. It's based on Volume 1 and has scenes we've never seen before. Does that mean this adaptation will be a bunch of extras from Volume 1? Or does it have a story to tell? Will we learn about the secret in the trailers as flashbacks included in each chapter rather than actually adapting the entire trailers?

We'll just have to wait for more. Miwa did a decent job. The weapons and the Grimm look pretty good but as expected from Miwa... the character designs look very weird. Especially Cardin at the end. Meh. I'll just get used to it.
