Nono-chan

The Yamada family consists of Miiko, her brother Mamoru and her parents. Both of her parents have work, so they are usually busy during the day and are outside of the house most of the time. The troubles in Yamada family are usually caused by Miiko's lazy character and her clumsiness.

The manga is set in Matsuyama City in the southwestern prefecture of Ehime on Shikoku Island during the Showa 40s era (1965-1975). The Onda family includes the big sister Sachiko who is a passionate fan of the idol Hiromi Dō, the little brother Takushi who is terrible at arithmetic, the father Yoshito who works at a factory and is a Yomiuri Giants baseball fan, the mother Natsuko who wants to build a house for the family, and the newest addition — a cat named Mii.

A year has passed since "Okawari" and the 3 sisters have grown up. Their likings and mods are almost the same, Haruka the older sister is a love-giving mother to the younger sisters, but she's also a discipline follower, Kana the middle one leaves everything to the last possible moment and always gives trouble to this trio, and Chiaki the little one is the calculating and manipulating one, she likes to be admired and loved by Haruka and always gives trouble to the less blessed Kana. An unbalanced family, but besides of that they love each other with their whole heart. This family's daily life is as funny as ever, trouble and love is always present, now its time to see if they'll survive this age change since Haruka is now a Young adult and she has even more responsabilities while having to watch over the younger while integrating to the adult life.

The Yomota family is small and typical: father Kinekuni (42), mother Tamiko (38), and son Inumaru (17). One day, a beautiful girl appears at their front door, calling herself "Maroko Yomota," granddaughter of Inumaru who travels back in time with a time machine to visit her ancestors. Even with Tamiko's strong objection, Kinekuni and Inumaru welcome her to stay with them, and the structure of a happy family has begun to collapse.
