Description

The Devil Is a Part-Timer! (はたらく魔王さま! Hataraku Maō-sama!?, lit. Working Demon King! or Demon Lord at Work!) is a Japanese light novel series written by Satoshi Wagahara, with illustrations by Oniku (written as 029). ASCII Media Works has published 15 volumes since February 2011. The story is about a demon king named Sadou Maou seeking to conquer the world of Ente Isla but, when confronted by the Hero Emilia, is forced to retreat through a gate that transports him to modern day Tokyo, Japan. To survive and find a way to return to Ente Isla, Satan gains part-time employment at a fast food restaurant called MgRonald.

Growth

2 measurements spanning 66 days, net +1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 5–6 and does not start at zero.
