Video title: [Part One] Touhou Geneikyo [Embodiment of Scarlet Devil] - Touhou Geneikyo's first part of the story. "東方紅魔郷" in this sense means this part centers around the incident of EoSD, although that's not to say that this will be referenced later. 東方ニコ童祭 - Touhou Nico Dousai Touhou Nicovideo Festival. = Story explanation for now (From watching it through once.): Keine is shown to have some kind of illness, and Mokou is going out to resolve it. The scene switches to Sakuya and Marisa battling it out. It causes an explosion in the library, and Patchouli is annoyed a bit. There's a flashback of Marisa saying something about seeing her again, and Patche comes to the realization of something. Scene switches to Remilia fighting Reimu, and Remi casts Star of David as they begin, but Reimu starts to have some... flashes... and as she is stunned, she gets hit smack in the face with a bullet, to Remi's shock. Something starts to break and Komachi does something to fix it, under Eiki's command. What breaks, I'm not sure right now, however it just might be a barrier of memories due to the next scene ending at an inaudible Kaguya. Reimu is shown to have survived, looking stronger than before, nevertheless after saying "Remilia... you..." she falls to the ground below, putting Remilia in greater shock than before, and before she can get Reimu a flash of light stops her, and catches Reimu. Remilia becomes enraged, thinking it was all (chibi) Shikieiki's fault, as she was the one who caught Reimu. ... Look at the fucking size of that Eiki, I mean... even Nicovideo was laughing at her. It shows Reimu falling down, and goes to credits. After the credits are done, it shows the chibi Eiki dodging the enraged Remilia's danmaku. However, Remi is cut off abruptly at an attack from Mokou, who suddenly appeared, and the video ends there.
