Momoko Sakura is an elementary school student who likes popular idol Momoe Yamaguchi and manga. She is often called "Chibi Maruko-chan" due to her young age and small size. She lives together with her parents, her grandparents, and her elder sister in a small town. In school, she has many friends with whom she studies and plays together every day, including her close pal, Tama-chan; the student committee members, Maruo-kun and Migiwa-san; and the B-class trio: 'little master' Hanawa-kun, Hamaji-Bu Taro, and Sekiguchi-kun. This is a fun-loving and enjoyable anime that portrays the simple things in life.
