The "Hentai" Prince and the Stony Cat.: Henneko BBS

The Henneko BBS (Bulletin Board System) was produced in 2013 as part of the promotional materials for the anime adaptation of The Hentai Prince and the Stony Cat., or Henneko. Developed by studio J.C.Staff, the project was based on the light novel series written by Sou Sagara and illustrated by Kantoku. The series gained significant attention for its blend of supernatural comedy and the distinct, soft-hued aesthetic established by Kantoku’s original character designs, which J.C.Staff sought to replicate through vibrant animation and character-focused special features.

This specific item was released as an interactive web-based special intended to foster community engagement during the broadcast run. It provided a platform for fans to interact with the series' thematic elements and characters, reflecting the lighthearted, meta-narrative nature of the source material. Received well by the domestic Japanese audience as a creative extension of the show's marketing, it remains a snapshot of the era's digital promotional strategies for light novel adaptations.
