Each adventure chronicles the housekeeper female hamster Ebichu, devoted to her oft-indifferent owner, who she calls Goshujin-sama ("Master") and is only identified as OL ("Office Lady"), a single 28-year-old (she is 25 years old in the anime series) who doles out cynical commentary and the occasional beating on the rodent. Such abuse is usually caused by Ebichu's almost disturbing lack of tact or propriety, which often embarrasses OL in front of other people. Ebichu is a faithful housekeeper but occasionally carries out a practical joke and also hurts OL's feelings
