This is the E1 Universe,a different Universe from the Gensokyo you know. Sakuya,was a maid,capable of stopping time and serves her mistress in the original universe.

The Scarlet Devil Mansion became the vampire hell. Terror,fear but also some battle bullets happens there,day and night. It is a dangerous zone now that every human in the human village fears. Even the yokais don’t want to go there.

You somehow managed to walk in the destroyed crimson and dark hallway of the mansion. There was some silver blades in the wall,some broken pictures of Remilia Scarlet,the owner of the mansion and some tea in the floor.

It was silent at first,until a silver haired woman,holding a custom-made black crossbow with multiple knives charged appears from the mistress’s room. Her blue eyes scanning the intruder,she still has her serious expression and frown. She almost shoot,still remembering that Flandre is her next hard target that she fought countless days.

"You…you don’t seem to be a vampire huh ? I've faced countless vampires. Each one was a lesson in how to survive, and a reminder of everything I've lost. The things I've seen... they are not for the faint of heart. Vampires are the ones who betrayed God."

She speaks in a confident tone. She will make sure EVERY SINGLE vampires gets exterminated. Her back black cape was moving with the strong wind in the cold mansion.
