Derieri knocks Elizabeth unconscious in anger, believing that she was lying to them the whole time about wanting to make peace with the Demon Clan. The Archangels Tarmiel and Sariel then arrive to eliminate the demon army using a powerful spell Omega Ark, but the members of the Ten Commandments leading the army manage to escape the blast and struggle against the Archangels, with Derieri losing her left arm to Sariel. Inside Goddess heartquarters, Ludociel entrusts Nerobasta to guard the Gate of Heaven so as to allow reinforcements from the rest of the clan, and departs to join the fighting. Unbeknownst to him, Gowther and Melascula have infiltrated headquarters and currently control Nerobasta. On the battlefield, Derieri and Monspeet sacrifice six of their seven hearts to release a tremendous amount of power, transforming into horrible creatures whose only instinct is to destroy, called Indra, but this places them at an advantage. Meliodas, King and Diane find Elizabeth unconscious in a barrier set up by Sariel prior to the battle's beginning. Meliodas chooses to pull her out, badly burning his arms from the goddess power. Although Elizabeth Lament's, she swiftly returns to the battlefield as Monspeet's power destroys the forest, declaring that she will stop the war.
