How Not to Summon a Demon Lord

Takuma Sakamoto was a shut-in gamer who achieved renown as the Demon Lord in Cross Reverie, a MMORPG, for his overwhelming gear and skill.

After awaking to hands filled with breasts, Diablo follows Shera and Rem to register as new members of the Adventurer's Guild. While Shera is identified as a level 30 Summoner by the guild, Diablo's level proves too high for them to measure.

The Warrior Emile, defender and ally of all women, challenges Diablo to a fight.

Rem, Celestine, and even Emile struggle in their battle against Gregore's sudden attack. Meanwhile, Diablo and Edelgard confront each other on the Bridge of Ulug.

The Kingdom of Greenwood demands that Faltra City hand over Princess Shera. If they refuse it will lead to war, so Diablo meets with Galford, the Lord of Faltra City, and accepts a quest to prevent war from breaking out.

While Greenwood's demands remain unmet, Diablo and the girls visit a slave market to see if they can learn the magical secret of the Enslavement Collars.
