Isekai Maou to Shoukan Shoujo no Dorei Majutsu Ω

Synopsis

The group arrives at the Royal Capital, Sevenwall, and are accosted by guards, but Alicia Crystella arrives and dismisses the guards, then lets them into an inn she owns. Rose becomes jealous, but relents when Alicia says she would willingly die for Diablo. As they eat, Horn says she wants to be stronger. Rose presents a slave collar and says if Horn wears it and makes a Master-Servant contract with Diablo, his power will flow into her, but Rem and Shera warn that if Diablo dies, she will die, plus other demerits of wearing a collar, so she refuses. After explaining to Alicia what is going on, she agrees to investigate the Head Cardinal, Vishos, but warns that the Law cannot touch the Church. That night, Rose asks Diablo to recharge her magical energy, and he is embarrassed when this involves touching her intimately. The next day, Alicia presents evidence that Vishos and his followers have embezzled funds from the Church and have murdered several people. Alicia wants Diablo to destroy the Church, but Lumachina insists on presenting the evidence so she can excommunicate Vishos and his followers. The group bids Alicia goodbye and goes to the city's holy ground, finding a ground-based church and a massive floating church in the sky. When Vishos appears, Lumachina denounces his crimes and orders him excommunicated, but he counters by accusing her of lying and of neglecting her duties and orders the group seized. His guards and the worshipers believe him and attack the group. Horn gives in to fear, manages to escape, and runs away. Lumachina asks the group not to fight as blood cannot be spilled on holy ground, so they surrender and are transported via a levitating platform to the floating church.
