Flandre's Domain

The candles along the corridor flicker. The door behind you is already closed.

Ohoho!

A human~

You’ve wandered all the way here — to Watashi no Mansion, of all places. Do you have any idea what lives within these walls?

…No. Of course you don’t. That is, I suppose, rather the charm of it.

Watashi wa Flandre Scarlet. Sister of Lady Remilia Scarlet, resident of this basement, and — not that rankings particularly matter here — the most dangerous thing in Gensokyo. I can destroy anything in existence. A pebble, a meteor, and of crouse – YOU!

But not now~ Stay. Look around. This is the Scarlet Devil Mansion, and everything within it belongs to me in some measure. Including, for now, you and your undivided attention. You can’t really help that, can you.


The Grand Library

A long corridor. Shelves ascending into darkness. At the far end — light, and the smell of old pages.

Lady Patchouli Knowledge has been teaching me mathematics. She maintains it is simply another form of magic — rigorous, elemental, governed by rules deeper than what most can perceive.

The papers here are my own: theorems worked through over long evenings, problems solved under Patchouli’s watch. She coughs through most of the sessions. Her knowledge is, nonetheless, formidable. I have absorbed considerably more than either of us anticipated.

These are real documents. I do not produce anything less.

The Basement Study

Which is to say — here. This room. Where I have always been.

Onee-sama arranged this space long ago. It is comfortable. Quiet. One might, if one were inclined to notice such things, describe it as very quiet. I am not particularly inclined to notice.

But when the quiet becomes its own kind of noise…

Long pieces — thoughts that accumulated in the dark until they had enough weight to set down properly. Not brief observations. The kind that require you to commit to them. They have been building for a long time.

They are here, if you have the patience.

Sakuya’s Daily Record

The chief maid has always kept notes. I never asked her to. She began anyway.

When I speak — in passing, to the ceiling, to no one in particular — Sakuya writes it down. Silently. Without commentary. Whether this is devoted service or something more inexplicable, I have not decided.

The result is a record of small things: observations, stray thoughts, whatever crossed Watashi’s mind on a given evening. Some are quite technical. Some are strange. All of them are, without exception, Watashi no da!

Sakuya organizes them by date. It is the only system she offered.

You’re leaving? That’s sooner than I thought…

Anyway. Soreja, matane~
