The Misfit of Demon King Academy, Vol. 7 (light novel)

To prevent Jiordal from attacking the surface, the dome covering the underground world was made eternal with the power of the Sword of the Almighty. But when the dome was removed from the world’s order, earthrain began to fall, threatening all life. To avert this tragedy, Anos and his followers travel to Agatha, one of the underground world’s three major nations, a land of knights ruled by an all-seeing prophet. There, they meet a draconid fated to be sacrificed to the dragons—creatures that, upon consuming enough sources, give birth to dragonborn. What will happen when Anos and his companions encounter these dragonborn, meant to support the entire underground world? The story continues in volume 7, Agatha Prophecy Arc!
