The first promotional video for Hoppe-chan: Sun Oukoku to Kuro Hoppe-dan no Himitsu has been released, offering a glimpse into its whimsical world. The trailer showcases Ganso Hoppe-chan, a protagonist who has lost her memory, navigating the "cuteness"-centric Sun Kingdom. Her journey is intertwined with Hoho, an office worker in the real world struggling with her own sense of self-worth, suggesting a narrative exploring themes of identity and resilience.
Produced by Toon Harbor Works, the series is set to be a 12-episode fantasy adventure. The PV highlights the conflict against "toxic Hoppe-chan creatures" that threaten to make the Sun Kingdom an "uncute place," positioning Ganso Hoppe-chan as a key figure in the "Guardians" fighting back. The anime is slated for a Winter 2026 release.
