Touhou/Crossover

As Rule ⑨ says: "If it exists, there's a crossover with Touhou". This is an attempt to document them all. Well, not really -- that would be stupid; it's an attempt to document at least one crossover per work.

For further reading, please refer to, this, this and this.

Notes On Adding Examples:
 * Categorize the crossovers according to the category of the original work being crossed over. Avoid listing MMD videos if a crossover is available in another form.
 * Link the crossovers to the new Touhou Wiki if there's an article available
 * Try to keep NSFW links to a minimum. If it's an image found in Danbooru, check if there's another one in Safebooru; if not, then use Danbooru. Even so, try to use images with a Safe rating as much as possible. Indicate if it's either Danbooru, NSFW, or both.
 * If it's a fanvid or a picture, indicate the name of the original work; if it's a whole new game, film, manga, etc., indicate the title of the crossover, then indicate the original work in parentheses beside it. Both are followed by a on the right. Indicate the notes in parentheses beside the link if there are any.
 * For the sake of accessibility, please avoid Nico Nico Douga or Pixiv links. Instead, use Safe/Danbooru or Youtube alternatives.
