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 Yamada sisters, Kyo (15) and Asu (9), are students studying in secondary and primary schools respectively. Their mother passed away and their father ran away after incurring gambling debts. Despite the difficult circumstances, both of them decide to overcome the unhappiness and welcome their days with enthusiasm and pride. Fortunately, with the change in the law system several years ago, Kyo is able to study and simultaneously take temporary jobs (such as distributing newspapers and tutoring) to make ends meet. On the other hand, Asu takes charge of household chores, prepares meals, and manages the finances to assist her older sister. Surrounding them are also good and kind neighbors such as the novelist, Saegusa-san, and the aunt at the public bath who watch over them. Although life is difficult and at times painful, the sisters are happy to have each other.
