Demon Lord, Retry!

What do you do when the MMO you've run for 15 years comes to an end? Akira Ono didn't get much of a choice - he woke up trapped inside the world of his own game in the body of his in-game character: the Demon Lord. With an outcast child as his sidekick, he tries his best to survive the cruel fantasy world of his own creation, prosecution from the good guys, and of course, the final boss.

After defeating the Satanists, the Demon Lord meets White—the oldest of the Holy Women—who also fears the Demon Lord's powers much more than she should. Oblivious to this, the Demon Lord works hard to develop Luna's village. He begins by building all sorts of non-fantastical facilities, like a field hospital and a hot springs resort, when...

Leaving the village of Rabbi in the care of his advisors, the Demon Lord heads north with the adventurers Yukikaze and Mikan in search of an anti-magic solution. However, he enters the Bastille Dungeon during his search to find an unimaginable sight. At the same time, the village development steadily becomes an international success with the help of the influential Madame. Get ready for the third volume of the mistaken-identity fantasy, where a game developer plays a Demon Lord of his own creation!

After defending the city of Rookie from the monsters of the Bastille Dungeon, the Demon Lord decides to seek more answers about this world. He infiltrates Animania with his newly summoned advisor, the two Star Players in tow. Meanwhile, Luna receives news that her childhood best friend, a demi-human, is being shipped to Hellion territory as a slave. Can Luna save her best friend before the fanatical Tzardom of Light carries out their plan? The Demon Lord and party approach the core of the mystery behind the world of Akira Ono's creation.

Having rescued Luna's childhood friend, a demi-human named Eagle, from the Tzardom of the Light, the Demon Lord finally advances through Animania into Hellion territory, finding himself in a slave market. He launches a full-on war against the Hellions in order to free the enslaved humans. What will happen when the Grand Devil Belphegor, Olgan's father, hears word of this? The Demon Lord plunges further into the turmoils of this fantasy world, as he continues to search for the truth behind this world and his place in it.

After defeating the Grand Devil Belphegor, the Demon Lord returns from Hellion Territory to his home-away-from-home, the Village of Rabbi. There he summons yet another advisor, this time to handle the maintenance and management of the village. He had hoped to finally make space for some quality time with the friends he's made in this world, but his well-deserved R&R is cut short when one of the four major political factions in Holylight sparks civil unrest.

With the leaders of Holylight under his thumb, the Demon Lord decides to summon yet another member of the Sleepless Castle: Ren Miyaoji, Akira Ono's most beloved advisor. After a brief reunion, they travel to Euritheis, where the mafia-owned company Jack of All Trades reigns with drugs, gambling, and human trafficking. The Demon Lord, the walking embodiment of hijinks, soon draws the attention of this company, and then...

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.

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 Donas stronghold to rescue the captive, tortured children called the Numbered. The militant nobles launch their counterattack, and the Demon Lord begins his conquest!

The central nobles of Holylight were lured to war, baited by false signs of weakness in the militant nobles. Little did they know, the Demon Lord had come to save the Numbered children, and greeted the central nobles with annihilation. The Demon Lord's first act as the de facto ruler of Holylight was to redistribute the wealth that had been hoarded by the central nobles for 2000 years, jumpstarting a new golden age for the nation. During the fallout of these events, the Demon Lord finally summons Tahara's sister Manami to this world. Their moment of peace would be short-lived, however, as another fierce battle fast approaches.
