Nobue Itou may be attending college, but her real lessons come from dealing with her 12-year-old sister Chika and her equally adorable friends. There's Miu Matsuoka, the troublemaking girl next door who's never found a diabolical plan that she wasn't willing to hatch. Then there's the perplexing Ana Coppola, who was born in England but has lived in Japan for so long that she's forgotten most of her English and is unsuccessfully attempting to re-learn her British heritage based on some rather erroneous assumptions. After those two handfuls, shy, sensitive Matsuri Sakuragi should be a welcome dose of normality, but unfortunately Matsuri is also incredibly gullible. And then there's Chika herself, who's actually the most mature and sensible person in the Itou household… which comes in handy when her older sister attempts to raid Chika's savings in order to buy cigarettes! Get ready for a cute overload so intense that it can be used as a deadly weapon when slices of everyday life get whipped to frothy perfection in STRAWBERRY MARSHMALLOW!
