Japanese messageboard 2ch has many tales to tell, whether they be events unfolding in a thread or written stories. I've translated all kinds.
Red stories are threads that tell true stories (or at least they present themselves that way), usually with some conversation between the OP and other 2ch posters.
Blue stories are short stories written out and posted in a thread part by part. Many of these are comprised almost solely of dialogue between characters without proper names.
Green stories are by Fafoo, one of the few 2ch authors to identify himself, who later became published author Sugaru Miaki. His stories are in a more standard style, not using the "dialogue" format.
Given that it's 2ch, some stories are unavoidably risque, so take note of the warnings in the descriptions to see which ones aren't exactly for all ages.
