Isekai Maou to Shoukan Shoujo no Dorei Majutsu Ω

Synopsis

When the group arrives in Zircon Tower City, a child named Horn who had explored the first three floors of a newly discovered dungeon offers to be a guide; the description confirms it is Diablo's dungeon, implying it was summoned along with him. A woman begs a priest of the Paladin Brigade to heal her child of a deadly disease called Death Knell, but is denied because she lacks money. Diablo defeats the priest when he gets violent and Lumachina heals the child. A monstrous sand whale attacks the city and Diablo tries to fight it, but requires the help of Batutta and the city's leader, Fanis Laminitus, to drive it away. Batutta apologizes for his subordinate's behavior, but Fanis heavily taxed the church, making them desperate for funds. Fanis says God is not real and the Church are just swindlers. She tries to shoot Lumachina, and when Batutta blocks it, she says that since God did not stop her, that proves he is not real, then leaves. Lumachina is appalled that many people have Death Knell and are denied healing due to lacking money, but Batutta says they must be pragmatic. Batutta takes the group to his mansion and serves them food. While Diablo and Shera bathe, Batutta and his maid meet Rem and Lumachina for a discussion.
