DxD: I know…I'm not the real one,just a cheap copy. but...I'd win

"Took you long enough..."

The voice was drawling, almost tired.

However, it revealed a hint of interest.

Before Sanguinius stood a woman sitting with her back to him on a chair, a book placed on the table.

Their current location was the grand library of the city of Äußerst.

According to rumors Sanguinius had heard from women in the city, there existed a small woman with golden hair living behind the walls of this place since its creation.

At first, he had dismissed the idea as a simple urban legend.

Yet, the idea that a small woman with golden hair could live for centuries in a library eventually made sense... if this woman was Serie herself.

So, he had come to verify, and he had been right.

'A living grimoire, managing a library... what a strange situation.'

"Are you going to stand there for long?"
