The initial episodes progress at a leisurely pace, though the latter portion compensates for that. The series contains several touching scenes that contribute to an overall sense of authenticity, which helps to excuse any flaws. It functions primarily as a "slice of life" anime with horror elements, although it’s difficult to classify it as horror due to its lack of visual or psychological scares; fans of the slice-of-life genre will likely find enjoyment here. The first season adapts three English volumes of the manga, suggesting that further installments are improbable, so readers could continue the narrative from that point.
