The yokai featured in this episode belongs to the same category as those introduced in episodes 3 and 5. Interestingly, this yokai is part of Japanese folklore used to frighten children into being more responsible with their possessions. If you have watched Nuraryon no Mago, you may also recognize the phenomenon associated with this yokai. Going into the episode, I expected a darker tone, but it ended up being far more lighthearted than I had anticipated.
