Round eyes, sparkling cheeks, and a squishy texture— The character "Hoppe-chan," which became hugely popular among elementary school girls, is making a comeback in an anime! In the world of Sun Kingdom, built entirely on "cuteness," Ganso Hoppe-chan is a "lost" Hoppe-chan who appears there with no memory. Meanwhile, in the real world, Office worker Hoho is gradually losing her self-esteem amidst her daily work and life, becoming a "lost" soul in her own existence. Somewhere, something goes amiss, and the two stories quietly begin to unfold— Behind the scenes in Sun Kingdom, poisonous Hoppe-chans are creating a "place that isn't cute," and Ganso Hoppe-chan joins the "Guardians" who protect the kingdom... A parallel fantasy comedy about the revival of Sun Kingdom!
