Episode 4 is technically an improvement because it has a plot now. But that's a low bar. The dungeon crawl is generic, the animation is the worst it's been, and the Demon Lord confrontation lacks any weight. The episode ends with Satou formally making Liza, Tama, and Pochi his slaves, which is treated as a happy resolution rather than something to question . If you're watching this for relaxing fantasy vibes, it's passable. If you want coherent action, character development, or anything that feels like it was made with care, this episode won't deliver.
