The premise involves beings resembling humans who consume human flesh; these ghouls possess considerable strength and have unknown origins, drawing parallels to vampires in other narratives. A key distinction is the public awareness of their existence. Like many stories, it features an introverted and somewhat fragile protagonist unexpectedly drawn into this world of ghouls. Subsequently, a series of events unfolds, suggesting that either the writer or the anime’s production team lost focus and failed to resolve several plot threads. The shift between the second and third seasons feels jarring, with many characters merely mentioned later on. Numerous aspects remain unclear, as significant characters were introduced during the second season and substantial revelations occur near its conclusion. However, the motivations behind the central characters' choices are obscured by vague explanations that attempt to sound psychological. Despite the incomplete narrative, the animation quality is high and consistently well-executed, and the story initially moves at a pleasing speed. Nevertheless, I couldn’t continue watching beyond the initial episodes of the third season because the abruptness and unresolved questions proved quite frustrating. This anime might appeal to viewers who enjoy developing their own theories about what's happening, but those seeking a neatly concluded storyline should probably avoid it.
