After successfully taking down the fourth Demon King to stand against him, Astaroth sets out with Eve and Jeanne in search of coffee beans. But his leisurely trip turns into a new quest when he meets Ryoma, a half-elf woman who begs him to help save her father—the famous samurai Sakamoto Ryouma!

Astaroth’s winning combination of strategy and teamwork proves fatal for yet another demon king when Eligos falls before him! While Astaroth considers how to best utilize his new land, his people celebrate the victory as their king’s fearsome reputation spreads throughout the realm. There’s just one more order of business, though—summoning new allies to aid him in battle! What kind of powerful ally will join his ranks…?

Astaroth has been reincarnated into a strange new land as the seventy-second Demon King with a mission from a mysterious goddess to unite the world under his banner and reform its chaotic ways. With two demon lords now crushed beneath his heel, Astaroth's power is only increasing, but he's got no time to rest on his laurels. In search of a means to bolster his army even further, he heads to an abandoned ruin, where he comes across a mysterious boy…

The Reformation of the World as Overseen by a Realist Demon King is an isekai (another world) manga series involving a pragmatic hero who turns his new fantasy home on its head.

With Eve, Toshizou, and Jeanne by his side, brand-new Demon King Astaroth has already bested three other Demon Kings on his way to mastering and reforming the world. His next target is Zagan, a monstrous Demon King, but Zagan has a powerful hero on his side too—the son of Genghis Khan!

Astaroth’s new life as a demon king rising up the ranks in an unfamiliar world has only just begun, yet he’s already assembling quite a group of allies! With his maid, Eve, serving as his advisor, legendary swordsman Hijikata leading his forces into battle, and Jeanne d’Arc herself lending him her strength, it’s no surprise how quickly he’s making a name for himself. His next step is to recruit some talented dwarves to expand his castle town, but a fearsome necromancer stands in his way…

With Astaroth’s first victory under his belt, his rank as a demon king has increased, if only a little. Now that Sabnac and his castle are no more, Astaroth immediately sets himself apart from the rest of the demon kings with his new policies. Rejecting slavery and treating all his subjects as equals—even the ones who had sworn fealty to Sabnac—are just the start. Envisioning a grand city where humans and demons alike can live together in peace, Astaroth begins to put his plans to expand his territory into motion!
