Demon Lord, Retry! Volume 8 by Kurone Kanzaki

The Demon Lord and his party had little time to enjoy themselves in Euritheis. Scarcely have they defeated the Jack of All Trades before the Gorgon company approaches with an offer: twenty-one holy coins for Jack’s head. The Demon Lord pursues Jack only to find him sitting on the throne half-dead, accompanied by the high-rank devil Utopia, leader of the Satanists.
