Fanatics of the Water City Father Zesta is arrested on suspicion of collaborating with the Devil King by pouring jelly slime powder into the city's hot springs. However, he manages to pass a lie detector test an the authorities have no choice but to release him. Megumin then wonders who the real culprit must be. Arnes then arrives to take Chomusuke, but Zesta, Cecily, and the rest of the Axis Church go into a religious frenzy when they realize she is a demon girl and chase her out of city, believing she is the culprit sabotaging the hot springs. Zesta then gifts Megumin with enough money to pay for a coach trip to Axel, and offers to have her stay the night. Cecily reveals to Megumin that Father Zesta had accidentally mixed jelly slime powder in the hot springs instead of baking powder, which was how he passed the lie detector test. Upon seeing how small the Axis Church's hot springs are, Megumin uses her explosion magic to create a much larger pool. The next day, Father Zesta casts a blessing on Megumin and she bids farewell to him and Cecily before leaving for Axel with Yunyun.
