Long story short the Demon King is a reincarnated Japan citizen with powers of making monsters stronger by ten fold ( Stated by Serena in volme 16 ) there is also a Demon King senior ( Stated by Serena ) but it's pretty vauge. It's probably elaborated more in the web novel but I guess we just got to wait for Volume 17 to be sure though.
