Oh? Is this perhaps a photo of you, Chief Maid...?

My, how nostalgic.

This was recorded when I came to the Scarlet Devil Mansion. How old was I at that time, I wonder.

Aha... Chief Maid, you were quite cute at that time, too, weren't you?

What's this? The tag is brand new.

Is this... a ceremony?

Yes, that's right. It was for the start of the construction for the Great Library of the Scarlet Devil Mansion. Originally, this here was the main building of the mansion.

The person over there is Mademoiselle.

With my ability to manipulate space and Miss Patchouli's magic, we remodeled it into the Great Library, which could contain the huge book collection.

An incredible operation...! And both of you have been keeping this large-scale magic up ever since?

Because Miss Patchouli is always in the library it's not a problem, but for me this isn't possible.

That's why a "medium" was fixed as a cornerstone in the deepest part. As my substitute.

A medium...

I wonder why Mademoiselle took out this blade.

... I see, now I understand. Koakuma, I may have found where Miss Patchouli is.

Really? Finally!

Maybe, okay?

But for today, let us take a break. We are very exhausted and have to warm ourselves up.

Aah~, right~... My MP is almost at zero.

Specially because drawing out the keystone is something very dangerous...
