Kurone Kanzaki 
Demon Lord, Retry! Volume 9 [EPUB ebook] 

Civil war in Holylight rages on. The Central nobles’ faction grows ever more violent and savage in their march, while the militant nobles draw them out with false rumors of dwindling supplies.

Meanwhile, the Demon Lord holds a meeting with the Gorgon Trading Company, unintentionally entangling his own mess further. Despite his sincerest desire to stay far away from conflict, he winds up storming into Dona’s stronghold to rescue the captive, tortured children called the Numbered.

The militant nobles launch their counterattack, and the Demon Lord begins his conquest!
