421 Isn’t this just like a secret organization!?

Hoshi was attracted by this song and wanted to find the girl who was singing.

While walking around in the forest, what he saw, heard, and touched all felt incredibly realistic to him, unlike any dream he'd ever had. It all felt tangible to him.

'This lucid dream is incredible!' That was Hoshi's opinion at the time.

In the end, he never found the singer by the end of his dream.

"After I woke up, I tried recalling for a long while if I had ever heard this song anywhere before, but I couldn't recall it at all. I found it quite strange why it appeared in my dream." Hoshi tilted his head slightly. "Perhaps it's that I heard it once long ago but forgot… at any rate, I was unable to recall."

A forest of maple trees, red leaves, and a female singing…

Seiji recalled a common SR-ranked spirit in the cell phone game he used to play in his previous world.
