The artbook is basically this.
The first few pages are a description of each character alongside their portrait.
The next few are design sketches of each character.
The next few are likely from the swimsuit contest in the game (haven't seen it yet, so I'm not sure.)
The last page is somewhat similar to the artwork on the cover of the Rorona premium edition, but it is Totori themed.
It's a short artbook and it is paperback. But it's okay.
The Atelier Series Chronicles covers the first eleven games in the series (Marie to Rorona), but not Totori or Meruru.
