Video Previews (Youtube)
Battle scene preview
This video showcases part of the battle scene of Chapter 1. You can see the pseudo-animated style of the series in action!
Chapter 1 playthrough
This is a playthrough recorded by Metroid 338 on Youtube. So far the playlist contains the whole main story of Chapter 1. It works well enough as a preview, but it’s highly recommended that you get the download version for much better framerate. It’s especially noticable in the battle scenes!
This video previews the Touhou Mecha Database, which contains information on the various mecha, characters and terminology that appear in the story.
