The Story So Far—

In the MMORPG Cross Reverie, Takuma Sakamoto was overwhelmingly powerful, and was able to role play so well that his performances were more boss-like than the actual bosses of the game. For this reason, he came to be known as the “Demon Lord.”

By defeating the Demon Lord of the Mind, Enkvaros, faster than anyone else, he obtained the super rare item, the 《Demon Lord’s Ring》. It was one of the ultimate pieces of equipment in the game, able to reflect all types of magic.

Then, one day, Takuma found himself summoned to a world that looked exactly like Cross Reverie! Having performed the ritual magic at the same time, the Pantherian, Rem, and the Elf, Shera, fought over which one of them was his Summoner. However, thanks to the Demon Lord’s Ring he wore, their magic was reflected, so the Enslavement Collar meant for him clamped onto the two girls instead!

Faced with Rem and Shera arguing, Takuma was at a loss of what to do. While he may have been a superior player back in the game, he couldn’t talk with other people if his life depended on it. After struggling with what to say, the words that came out of his mouth matched the Demon Lord role play he had used in the game:

“Cease your pointless squabbling. You are in the presence of Diablo.”

Soon after, Diablo found himself foiling an invasion of one hundred Fallen led by a Fallen named Edelgard, as well as an attack from within the city of Faltra at the hands of the Fallen named Gregore. Diablo then found himself the recipient of a quest from the governor of Faltra, Galford. Prince Keera of the Elven Kingdom of Greenwood demanded Shera be returned to him, threatening open war with Faltra should Diablo fail to comply. The details of Galford’s quest were simply to find a way to avoid the war. The bespectacled, straight-and-narrow Imperial Knight Alicia was assigned to the group as an observer to watch over their actions.

Using the 《Marionette’s Flute》, Keera manipulated Shera and unleashed a forbidden Summon called the Force Hydra—yet Diablo still managed to rescue her.

After her rescue, the group set off to resurrect the Demon Lord Krebskulm trapped inside Rem. However, in the process, Krebskulm had lost a portion of her memories as a Demon Lord, being reduced to a biscuit-loving young girl who they nicknamed “Klem.”

Peaceful days passed by...

Suddenly, Alicia betrayed the group! Now awakened as a true Demon Lord, Klem went into a destructive frenzy. But thanks to one of Diablo’s ultimate spells and the sound of Rem’s and Shera’s voices, Klem was subdued and reverted to her biscuit-loving form. To ensure Klem would never go berserk again, Diablo bound her with the same enslavement magic inflicted upon Shera and Rem.

Through a string of coincidences — or perhaps God’s own guidance — Diablo found himself rescuing Lumachina, a holy woman, from the Paladin Gewalt. As High Priest, Lumachina was the highest ranking member of the church. However, due to her attempts at ridding the church of corruption and avarice, she was nearly assassinated. Still seeking to reform the corrupt church, Lumachina sought the help of the Paladin Captain Batutta, setting out to meet him in Zircon Tower, which was located in the perilous expanse of the former Demon Lord’s Domain. Diablo’s group of adventurers accompanied her as bodyguards. After a long journey, they arrived at their destination, and were greeted by Batutta.

While there, Diablo reclaimed his own dungeon, gained many pieces of helpful equipment and items, and fought off the new Demon Lord’s army, gaining new allies in the process: the Grasswalker, Horn, and the magimatic maid, Rose.

Shortly after, Horn decided to change classes and study to become a sorcerer, leaving for the magic academy.

However, they could not celebrate their victories. After being informed that the Elven king, Shera’s father, had passed away, the four traveled to her homeland, where Shera was already engaged to a pig-faced Elf called Drango (for the sake of the country, of course). Diablo thwarted the wedding, giving Shera a wedding ring and assuming the throne as the new king of Greenwood.

Diablo then fought and defeated his next great opponent, the Demon Overlord Modinaram. Saving Rem, who had been taken captive by Modinaram, he gave her a wedding ring.

News of Diablo’s heroic deeds reached the king of Lyferia, Delouche Xandros. Diablo attempted to ignore the order calling him for an audience with the king, but still begrudgingly found himself in the audience chamber one way or another. What awaited him in the castle wasn’t words of praise, but gazes full of suspicion. Left with no choice, Diablo accepted a quest from the king as an adventurer in order to guarantee his and his companions’ safety.

His quest led him to the southern frontier town of Caliture. This turned out to be Rem’s hometown, and the place where her family, the Gadou Clan of martial artists, resided. There, Diablo found himself being toyed with by Rem’s aunt, Solami.

“You can be confident. You’re certainly a Demon Lord on this front. Nobody could compare to this overwhelming strength♥”

And so, she trained him in the use of the Glow.

The king’s quest involved slaying wild beasts, but their targets turned out to be a clan of Kobolds. Being therianthropes, they were incapable of conversing with the races. But to Diablo’s surprise, he found he could understand what they said.

The Kobolds saved Diablo and his group when they were stranded, even giving them food and beds to sleep in, earning a debt of gratitude with Diablo, who decided to help protect their lifestyle. However...

The governor of Caliture wouldn’t budge from his decision to exterminate the Kobolds in the region, forcing Diablo to finally break away from Lyferia’s army. Rem and Shera faced off once more against the Palace Knight Gewalt, but the gap in their abilities only seemed to have widened.

Rem uses the 《Demon Lord’s Fang》 she previously received from Klem to become a quasi-Demon Lord, shocking Diablo by easily beating Gewalt with overwhelming power. Having exhausted her strength, Rem fell into a comatose slumber, only for Shera to shock Diablo further.

“I, uhm. I saw it. I saw what you... did in the courtyard with Solami... last night.”
