Rizel was developed as a secret government project. She has stopped growing so she has the body of a 12 year old and has a happy-go-lucky personality. She started living with Iwaki and everytime she cries she destroys a part of the house, Because her tears are bombs. She is considered cute and friendly by many of her classmates. She chose Iwaki as her husband and needs his love to be able to continue her growth. She is often chased by Hojoin Ryunosuke, for her innocence and her cute panties. (Source: Wikipedia)

Iwaki Tomonori is an average 15-year-old boy who likes older women. He happens to have a crush on his teacher, but soon thereafter, learns she has become engaged. He heads home brokenhearted, only to find a 12-year-old girl named Rizel at his home, who he learns the Japanese government has married him to against his will. Furthermore, he learns Rizel is no ordinary girl; she is a biochemically engineered human, and her creators (her "papa"s, as they are often referred to) promise to waive multiple bills of Iwaki's parents in exchange to be allowed to stay at their house, and thus Iwaki's life with Rizel begins.
