Name: Uso Ibun
Setting: A book whose content apparently changes depending on the reader.
If you read it without thinking, it’s a disappointing setup that just keeps going with endless four-panel comics that have no punchline.
Although the content varies each time, it’s unclear whether it will ever become interesting.

Among the higher-tier items is the “U=Su Ibon,” which reportedly manifests the reader’s desires, wishes, and fantasies as part of the work.
