Summary
"NT4's cover rough. This cover did not have a single recognizable character and I could not even put Kamijou on the color pages in order to avoid spoilers. Having no connection to past volumes seemed like a problem, so I made Kihara Ransuu look a lot like Kihara Amata. Marian had appeared before, so one idea was to put the Gremlin Trio on the cover, but these three gave the cover a lot more impact, don't you think?" ―Kiyotaka Haimura
