Rumors from Japanese industry insiders (via aniX chatter) suggest that Mokumokuren, the author, demanded an "exclusive animation" contract. This prevents the studio from outsourcing key animation frames to third-party foreign studios. It means the character acting—specifically the subtle twitches of Hikaru’s "thing" pretending to be human—will be drawn by in-house key animators.

While a full anime series has not aired, the franchise has moved beyond silent manga pages into audio-visual media, specifically through "Manga Motion Comics" and the PV mentioned above.

  • Significance: The selection of high-profile voice actors for promotional material strongly suggests that the publishers (Kadokawa) are testing the waters for a full-scale anime production, or that pre-production is further along than publicly announced.

    • The entity is not a ghost in the traditional Japanese sense (like a Yūrei), but something more biological and eldritch. The anime’s exclusive designs for the entity’s true form move away from standard CGI integration, which often creates a jarring disconnect in 2D animation.

    Instead, the teasers showcase a mixed-media approach. When the entity loses control, the animation style shifts—colors invert, and the lines become chaotic and sketch-like, resembling a corrupted video file. This visual metaphor suggests that the entity is a corruption of the natural order. This is best exemplified in the "mountain" scenes, where the environment itself seems to pulsate, suggesting that the village is not just a setting, but an extension of the entity's digestive system.
