When I was just summoned into the world as a Ruler, my goal was to be a capable, dedicated arbiter.

(The groundwork in the early chapters leaves the protagonist with painfully little screen time... If you're okay with this large cast, please keep reading...)
(Of course, if you've read the original and aren't used to such a long storyline, feel free to skip some chapters, or just start at Chapter 45!)
