Iwaki is a normal 15 year old boy in his third grade of junior high-school with a thing for older women. The reason is when he is a child, he tried to save Rizel when she was about to be hit by a truck and when he wakes up Rizel is hugging him. He has a long standing crush on his homeroom teacher, Natsumi Ibata. He was forcibly married to Rizel by the government. When Rizel starts appearing at school and claiming to be his wife, his friends are jealous of such a girl being ensnared by Iwaki already and start calling him a pervert. Despite his rather brash nature, he has a tendency towards chivalrous acts. (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.

The government has been conducting experiments to genetically engineer a human. Its first creation is a girl named Rizel, and the experiment is a success--sort of. 
While healthy and cheerful, 12-year-old Rizel also possesses the uncanny need for love to further her development. Saddened by this emptiness in her life, she sheds tears that can end up destroying a city block. 
So what's a girl to do ... except get married! Enter Iwaki Tomonori, your average 15-year-old boy. His world is turned upside-down the day he arrives home to find that the government has just announced that he's a married man!
