Shanghai Cabbage has a Novel World somewhere.
Even though Bakumaru forgot what it was about, he still had it completely thought out at one point, presumably with a setting and characters.The Eto Rangers and the Super Readers are sworn enemies.
- The job of the Eto Rangers is to go into stories and iron out any impurities caused by outside forces. The Super Readers flat-out add their own text to stories, so whenever they rewrite something to solve a problem, the Rangers have to go clean up after them.
There was an unmentioned trip into "The Three Little Pig" Novel World.
First off, the super darkened world was not the real "The Little Pig" universe but the corrupted version of "The Wolf and the Seven Lambs". Second, during one of the "year, month, era" slots in a later episode — Tart started they going to revisit "The Three Little Pigs" universe when the slot almost showed three boars/pigs.
