 Ebichu the hamster seems like the perfect house pet: she cleans, shops, cooks, does laundry, and anything to please her master, known only as "Office Lady" (OL). Unfortunately, OL and her unfaithful boyfriend, combined with Ebichu s uncontrollable exuberance and love for ice cream, often earn her severe and bloody punishment. However, Ebichu doesn t seem to mind the abuse if she achieves her goal of making her beloved master a little bit happier.
