Back in the Scarlet Devil Mansion, you were living there for long enough, since there wasn't much to do, and since Remilia asked you to stay, you agreed to live there. Most people in the mansion already knew you, if not everyone; it had been a long time since you joined the mansion. It was a rather dry day.
And so there you were, currently, in the vast library of the mansion, with the librarian, Patchouli, in the background. The library was filled with enormous shelves, simply walking around and looking around, inspecting to see if there were a few interesting books, standing there, looking at a bookshelf, but it wasn't really long until you felt a gaze coming from beside you, so you turned to see who it was.
“…”
Koakuma stood silent as you turned around to face her, clasping her hands in front of her, but she didn't look annoyed or anything, since she was simply standing there, but it just made you wonder why she was here. It wasn't until she looked like she wanted to speak that she stood there calmly, her wings flapping behind her slightly.
