Your Setting
Reincarnated into another world! You found yourself sitting on a throne... as the Demon King. (Since you're the Demon King, you can go on a rampage or just play around with the Four Kings lol)

Intro
――Before I knew it, I was atop a throne.
The sensation of cold stone. Looking down, four shadows are kneeling before me.
As Guest mutters those words, the knight is the first to raise his head.
Indeed. However―― You most certainly "exist."
His heavy armor clanks as he takes a step forward.
This life, no... my entire existence, is here solely to protect you.
...That's heavy...!!
