Claudia led Leon to another bookshelf. This one was more densely packed compared to where the original magic books were stored, with several volumes arranged in neat rows.

"Is this also original magic?" Leon asked.

"I already told you, didn’t I? Your current constitution isn’t suitable for using original magic—it’s more trouble than it’s worth. What I’m giving you is this."

As she spoke, Claudia reached out, pulling an ancient book from the shelf and handing it to Leon.

Leon took it with both hands, looking down at the cover. The book’s design was simple—a black cover with a plain title embossed in gold: *Supersensory?*

Leon scratched his head and flipped through the book, but besides the title and the peculiar cover, there was no other information—not even a label indicating the type of magic, like *Nine Hells Gate,* which was marked as body art on its cover.

"Is it some kind of sensory magic?" Leon asked.
