How Not to Summon a Demon Lord

Isekai Maou to Shoukan Shoujo no Dorei Majutsu

In the fantasy MMORPG Cross Reverie, legendary player Takuma Sakamoto reigns supreme from his own personal lair with his incredible gear and skill. While a feared demon lord named Diablo in game, he is a reclusive shut-in in real life. One moment he is in his room playing and in the next he suddenly finds himself at Skyfall Tower, a location within the game. The tower is a place that players can obtain rare summons at and it appears that the elf Shera and the pantherian Rem somehow brought him to this world.

1. The Demon Lord Act 2018.07.05
When the standard enslavement command backfires due to Diablo's powerful magic resistance ring, the two girls are suddenly bound to him instead. Diablo quickly realizes his incredible level and gear advantage has transferred over, apparently making him one of the most powerful people in the game world. When Rem realizes this, she shares with him the reason that they underwent the Summoning Ceremony.

The trio decide to go to the city's adventurers guild so they can begin accepting quests. During a routine magical affinity assessment, Diablo scores off the chart prompting the guildmaster Sylvie to meet with them personally. She gives them a quest to slay a Madara Snake in the Man-Eating Woods for a much larger reward than the newbie quests would yield. Arriving at their destination, they are ambushed by elves wanting to bring Shera home, who just happens to be the Princess of Greenwood.

3. Fallen Assault 2018.07.19
To make up for the last unfortunate quest, Sylvie offers the group an easy quest with an absurdly high reward - to simply deliver some food to a nearby bridge fort of Ulug. Upon leaving, they meet a pompous mid-level knight named Emile Bichel Berger, whom the two girls are already acquainted with. The situation at the bridge is gloom with a massive army of demons referred to as the Fallen headed that way. Diablo realizes the defense at the bridge is too pathetic to stop the Fallen army so in contrast to his adopted character, he decides to stay and help.

4. Point-Blank War Dance 2018.07.26
Back in the city of Faltra, trouble brews for Rem and Celes, the mage guild leader. Celes's former lackey, Galluk, was tricked into becoming an avatar for a Fallen after bitterly losing his battle against Diablo earlier. Just as they are about to be cornered, Emile swoops in to save them. Back at the Ulug Bridge, Diablo fights at a level that is astonishing to everyone - even the leader of the Fallen army, Edelgard. When Diablo hears that a fallen has infiltrated Faltra, he knows he must stop taking it easy on her so he unleashes a devastating White Nova to quickly put an end to their battle.

5. Imperial Knight 2018.08.02
The King of the Elven lands has demanded Shera's return and if Faltra fails to comply, it would risk war breaking out with the human Kingdom. To compound their troubles, the elf King's son, Prince Keera, has placed a large bounty for Shera's capture. In search of a peaceful resolution, Faltra's lord of the city, Chester Ray Galford, has summoned Diablo to return Shera home to the elven forest. To aid in their new quest, the Imperial Knight Alicia Cristela was sent from the royal capital to join them.

6. Slave Market 2018.08.09
A slave caravan has come to Faltra and Diablo takes the detour to find out if the Slave Collars could be removed from Rem and Shera. The owner is a woman named Medios and after she explains the process of unraveling the magic binding the collars to its host, Diablo realizes he doesn't yet possess the skill to remove them. Later at the inn, Keera Greenwood himself appears to reclaim his younger sister.

7. Change of Heart 2018.08.16
Keera's flute has an odd effect on Shera, making her earlier conviction to stay with Diablo fade away. Convinced by Rem to go after her, Diablo finds them in Keera's tent and uses his control over Shera's Slave Collar to break the flute's spell. With his back against the wall, Keera uses a forbidden ancient elven magic to summon a Force Hydra.

8. Hero's Charge 2018.08.23
Unlike the earlier pushover opponents Diablo has faced, the Force Hydra has an incredible rate of regeneration between each of its heads. Familiar with the elven summon, Shera tells Diablo there is a crystal hidden somewhere in its body that will break the summon when destroyed. Unleashing his full magical arsenal, Diablo destroys the beast and rescues Shera but they aren't out of the woods yet. Eager to exploit the war between elf and human for his own personal gain, Galford arrives with an army of his personal guards at his back.

9. Holy Knight Tale 2018.08.30
Back at the Imperial city of Sevenwall, Alicia encounters the knight Saddler, who is also departing for Faltra to investigate the head priest's prophecy of the Demon Lord's return in a western city. While out with Shera and Rem, Diablo is approached by Edelgard who has a method for releasing Krebskulm without harming Rem.

10. The Demon Lord's Resurrection 2018.09.06
Three nights later, Edelgard meets Diablo at Starfall Tower and begins the Resurrection Ritual. The awkward ritual requires a degree of closeness to Rem in order to send enough magic into Krebskulm. With a bright flash, the terrifying Demon Lord pops into place before their very eyes and isn't quite what anyone is expecting.

11. The Young Girl Awakens 2018.09.13
Spending her days filled with eating biscuits, Krebskulm, is failing spectacularly in her role as the Demon Lord. Alicia sneaks Klem away with Rem following closely behind. It turns out her true intention is the proper resurrection of Krebskulm and when Saddler shows up, she uses him to her advantage by accusing Rem of being a demon worshipper. Knowing he will need help to get Rem and Klem back, Diablo has to sink to a new low and asks Emile Bichel Berger for his assistance.

12. Battle for Legitimacy 2018.09.20
Now in her true demon form after watching Rem's torture, Krebskulm rampages in the middle of Faltra. A combined effort saves Rem and distracts Krebskulm long enough for Diablo to get off his trump card spell- Apocalypse Abyss. Being reunited with Rem, she quickly reverts back into Klem. Sylvie isn't exactly okay with allowing The Demon Lord to run around in the city so Diablo suggests using a Slave Collar to ease her worries.
