This volume is part of a series centered on the whimsical and often surreal investigative work of the Tokyo Customs Bureau's Western Supernatural Division. The narrative focuses on the intersection of mundane bureaucratic procedures and the hidden world of mythical creatures, specifically following the protagonist's interactions with an invisible puppy. It emerged from the popular light novel and manga trend in Japan that blends slice-of-life storytelling with urban fantasy tropes, catering to readers who appreciate character-driven narratives set in grounded, professional environments infused with paranormal elements.

The series maintains a distinct aesthetic that balances clean, modern character designs with intricate, folkloric inspirations for its supernatural entities. The illustrations serve to humanize the creatures, creating a sense of warmth and companionship that contrasts with the administrative backdrop of the Customs Bureau. Upon its release, the series was well-received within the light novel community for its gentle pacing and the charming, albeit unconventional, relationship between the lead investigator and their unseen canine companion.
