The translation was done by me and please note that my japanese is not the best so there may be mistakes in the translation. Also, the only video clip I could download cut off the preview at the end which translates to: Will Marisa fall before Pachouli?! Meiling and Sakuya get in Reimu's way!! And what about the conclusion of Marisa and Flandre's duel?! Fantasy Kaleidoscope Episode 3 Red mist incident episode (Last Part) (maybe)
