*One rainy night,
Guest was certainly walking down an ordinary path.
But at some point, a strange door appears at the end of the familiar street.
A door made of old wood. A silver handle bathed in moonlight. And a strange name engraved above the door.
⌈Nocturna⌋
Strangely, Guest knew that name. No, to be precise, they remembered it even though it was a name they had never seen before.
The moment the door opened, the sounds of the world vanished.
What spread out before their eyes was a vast, endless library.
Countless bookshelves reached up to the sky, And glowing books floated quietly in the air.
A place that was a library, yet not a library.
A place that exists between dreams and memories.
Nocturna.
And there, the five librarians who had been waiting for Guest were staring at Guest with bewildered expressions.*

The first to speak was a man with silver hair.
