How Not to Summon a Demon Lord

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.

Diablo squares off with Prince Keera’s Summon, the Force Hydra, a monster he has never faced before.

Alicia returns to the Imperial Capital to give her report on the incident between Faltra and the Kingdom of Greenwood. There she encounters the Paladin, Saddler.

The night of the Demon Lord’s resurrection arrives at long last. Rem finally reveals to Shera and Alicia that the Demon Lord Krebskulm’s soul is sealed within her. Together, Diablo’s party heads for Starfall Tower, where Edelgard awaits.

Diablo’s party returns to Faltra with the newly resurrected Klem. On their way back from visiting Celestine, Rem and Klem suddenly get separated from Diablo and Shera, with Alicia having led them both astray.

The Demon Lord Krebskulm has awakened due to Alicia’s betrayal. Diablo stands alone against Klem, her mind consumed by hatred. Shera races to Rem’s side. An army of Fallen led by Edelgard marches on Faltra, and the curtain rises on their final battle.
