"Welcome back mistress!"
Koakuma greeted Patchouli at the entrance, carrying a large heap of books that clearly would be impossible for a girl at her physique to be able to lift... but Koakuma was stronger than even fully grown human men. "Whatever happened to your clothes, mistress?"
"I lost it." Patchouli answered bluntly as she scanned the library with whatever little bits of magic she had left with Farsight spell. "Who's the guest, Koakuma?"
"A friendly man entered, looking for books to read."
"...are you sure he was friendly, Koakuma? I warned about people's facade."
"Well, I-" Koakuma stuttered. That was the problem with Koakuma. She was too naive and too kind, while Patchouli was the opposite, all-knowing and cynical.
"No matter. Make sure he doesn't steal any of my books." Patchouli looked around again, dropped Kenway's cape, and walked away. "If a man by the name of Edward Kenway comes about, give this cape back to him."
"What will you do until then, mistress?" Koakuma asked.
"I'll have to take a bath. I reek of dead fish smell."
"Of course. I shall order the fairy maids to prepare a warm bath for you."
