I kinda expected for the anime to ignore some of the story, and seeing as Liliana is quite popular, I guess they had to make up a reason to get her early into the story (though, her being the first char to appear is rather overkill)... but doesn't it seem too light-hearted? If they don't get a somewhat "dark and mature" tone soon, it won't be a "desperate fight against the tyranny", but a "happy adventure while sight-seeing".
Also, I seem to have missed this when it was announced, but the QB Perfect Visual Book is going to be
published in english. That's the databook with the most info on QB chars, every char's relationship with the others, a little world guide and the "endings" that were once translated.
