Meanwhile, in the real world, an office worker named Hoho is slowly losing her self-esteem in her work and life, sending her on the verge of becoming lost in life. Somewhere between Ganso Hoppe-chan and Hoho's worlds, their paths cross. Back in Sun Kingdom, toxic Hoppe-chan creatures are creating an "uncute place," and Ganso Hoppe-chan joins the "Guardians" to protect the kingdom.
