A modern-day Japanese housewife, who prides herself on a clean home, a balanced budget, and a frugal yet "tasty" dinner. Although at times she finds nifty tricks to multitask and consolidate household chores (like vacuuming the rug and waxing the wooden floor all at once), she is awfully clumsy and gets herself into sticky situations from losing control. Despite her hard work, she is also known for being somewhat lazy by taking copious afternoon naps, watching TV while eating senbei, and skimping out on shopping and/or cooking on rainy days. She often steps out on shopping trips and afternoon teas with her good friends Mrs. Mizushima and Mrs. Toyama. Additionally, they often take part in activities with (the more affluent) Mrs. Misumi. They often envy Mrs. Misumi's "rich" lifestyle and try to find "affordable ways" to be more stylish and upbeat. Her hobbies include shodou and cooking and eating chikuwa. She was also born in ÅŒita Prefecture. Her childhood name was "Banban". Although she had a childhood friend (that she liked a lot and hoped to marry), she was placed into an Omiai arranged marriage and married Father. She is also a very strict mother to her two children, and tries to have them waste less money/electricity/food, etc. Although she tries to make herself look more upbeat, she is very traditional in thinking when it comes to her daughter Mikan. (She won't allow pierced ears, staying out late for Karaoke, excessive fashions, and values housework over homework.) She is sweet on her younger son, however, and often lets him slide with things Mikan can't get away with.

Keita is a third-year junior-high school student studying for his high school entrance exams and although he is the younger brother, it is obvious he is the most mature of the three siblings. He wants to enter the same high school as his older twin step-sisters Ako and Riko, and to do so must study hard while getting help from his sisters as well as he was originally planning on relying on his track running scholarship for another school. While at first he initially dislikes himself for becoming attracted to Ako and Riko, he later becomes proactive in his desires. It is later revealed he was in love with his sisters when they were kids, and even used all of his money that he saved up for a prayer that he could marry both of them. This changed when he found out from his father that polygamy is illegal and "grew up". He is weak when it comes to alcohol, and will become livelier when he drinks, but after he sobers up he does not remember anything he did. After chapter eighteen of the manga, he makes it into his sisters' school Gakushū Senior High. He has strong morals (that have clearly weakened with the constant "attacks" his sisters have done throughout the series), as he will try to resist to the best he can, but if pushed too far he will simply indulge in the moment. He has also shown an attraction towards Miharu and Yuzuki. (Source: Wikipedia)
