Puzzled by the sudden turn of events, I returned my gaze to the cover of the book.

　I realized that the gold thread embroidery that I had thought was just for decoration was actually text.

The words spelled out as "A Collection of Magical Languages Useful for Everyday Life" were shining brilliantly on the cover of the book.

　--I'm not sure what I'm supposed to say.

''It's Japanese to the core!

　Yes, that's right.
　The "Japanese language" embroidered on the cover of the book with gold thread, and spelled with a mixture of hiragana and Chinese characters, was somehow incongruous to exist in this world.

　Why Japanese?

　While I wondered that, I opened the cover and found that I was able to read the contents of the book, which I hadn't understood before.

　The contents of the book are naturally in Japanese, and as expected, I almost fell down on the floor in a different way than I did a moment ago because of the predictable contents.

　As for the content, it's also much worse.
　To be briefly excerpted, "Hello," "Thank you," "Goodbye," "See you again," "The other side of the tunnel was snow country," "I am a cat," "Bodhisattva," "Inadvertently," ... it's a very trivial and unintelligible lineup.
　What kind of timing do you use "I am a cat"? Copyright.........has been expired, so it's not a problem, in this case?　I mean, it doesn't exist in this world........

　I was dumbfounded, but as I turned a few pages, a sentence suddenly jumped out at me: "Light, let the darkness shine.

'Light, let the darkness shine through.'

　Oh, I finally found an incantation-like phrase.
　It's about to get dark, so let's give it a try.

"'Light, cast your light into the darkness.

　At the moment I chanted, what appeared in front of me was a glowing yellow ball of light. It was about the size of the palm of my hand.
　The inside of the barn, which was dimly lit, was gently illuminated by the light ball.

''........Could that be magic?''

　I opened my mouth with a pop and looked at the light ball.

　But eventually I regained my composure and ran my eyes over the pages of the spellbook, which was made more legible by the light than before.

　I'm sure you'll find a lot of spell-like phrases in the book.

It's a good thing that you have a lot of experience in this field.

　.........well, they were all very difficult to say, and all of them were phrases that could be bitten by the tongue. As expected of a 'spell', the kind that makes you want to call it a 'spell'.

　Even so, if you utter these spells, the magic will probably be activated. I chose one to try and cast the spell again.

''Cover the light with darkness.''

　As I said it, I pointed to the light ball that was shining in front of me.
　It disappeared in a flash the moment he chanted the spell.

''Light, let the darkness shine through.''

　The light ball appears again.

"'Let the darkness cover the light.'

　The light ball disappears in a flash.

　After that, I tried a few other spells, but they all had some effect on me.
　Some of the spells didn't cause anything, but maybe the conditions for activating them weren't right.

　In any case, the fact that I was able to use the magic in such a blink of an eye made me open my mouth when I realized.
　The magic in this world is surprisingly choppy.

　I'm not sure if this is good enough for you, fantasy.
