Kanaka

This artificial intelligence assistant serves as a unique companion to the main character, assisting with mail delivery logistics. Possessing a distinct personality and the ability to levitate, the staff offers Fumika advice on deliveries, often clashing with her calm nature. In the anime, this AI has a boisterous female voice, while in the light novels, the male counterpart offers a condescending perspective. Despite being non-living, the staff insists on being treated as a person, making helpful yet sometimes error-prone contributions to the story.
