Chapter 0 of the Hotarubi no Tomoru Koro ni manga has now been translated, and can be downloaded here. The translation was done by Tarable Translations, who also did an excellent translation of the prologue short story. I scanned the raws and did the typesetting…so if something is screwed up, just let me know and I’ll fix it!
It’s basically like the trailer for a movie, with a very cinematic feel. On one hand, I find it rather intriguing. On the other hand, it doesn’t get into the story proper at all, and the series won’t be continuing until 3/25/2016. So for me this is a teaser trailer, with emphasis on the word “teaser.”
Disclaimer: If you enjoy reading these scanlations, please consider supporting the official English releases of 07th Expansion manga! Yen Press has published the manga for Higurashi, Umineko, and Rose Guns Days, and they’re all fine adaptations. Hopefully they’ll continue to get enough sales to release new series and spin-offs from Ryukishi07 in English.
