Reviewing the first two seasons of Animator Expo for Anime News Network, Kevin Cirugeda recommended the short "with reservations." He praised Tsurumaki's animation, but felt that the story overreached a little bit and attempted to fit too much content into its short runtime, writing that it showed "a glimpse of this fantasy world, but be warned that there's a larger story there that we'll never see." Salvador GRodiles of Japanator thought that the story was "a bit weak" but had interesting visuals, and had "potential" if Maijō were to  expand on it.
