After a twelve-year hiatus, the irrepressible housekeeping hamster Ebichu returns to service. Her beloved owner, known only as Goshujin-chama or OL, has finally married her long-term, unreliable boyfriend whom Ebichu nicknames Kaishounachi, and the couple now has a daughter named Ai. The household has grown, but so have its complications. Goshujin-chama and Kaishounachi face new marital strains and adult responsibilities, while Ai has become a curious and somewhat precocious elementary school student whose age gives her just enough information to cause trouble. As the family navigates the everyday absurdities of modern life—including work-from-home arrangements, mask-wearing, and the general chaos of raising a child—Ebichu throws herself into her duties with undiminished enthusiasm, boundless energy, and a complete lack of tact that frequently embarrasses her owner and invites physical punishment. Despite the beatings and scoldings, Ebichu remains endlessly cheerful and devoted, determined to keep the household running smoothly no matter what fresh disasters unfold. The sequel shifts the focus from single life to married life and parenting, maintaining the original series' signature blend of slapstick violence, crude humor, and heartfelt domestic comedy. Over the course of three volumes, Ebichu tackles everything from marital arguments to school events, always convinced that her brand of meddling is exactly what her family needs.
