Ryan Matthews has praised the cast choices in his column, saying that the cast is well-suited to their roles, but the performances were flat. He also notes that the ADR script was filled with clumsy wording and mid-sentence stops. He comments that it seems that the script was written without trying to match the animation. In his review, Zac Bertschy says that the series is highly original and very well executed. Bertschy praises the sound track. He notes that the character designs fit well with series' visual style and the characters' expressions were convincing. Although he says that the slow plot pacing is a more negative point, he points out that action is not the focus and that once the series' picks up, the "wait is more than worth it".
