History
Thus Spoke Kishibe Rohan - Episode 8: Deoxyribonucleic Acid
Fifteen years before the events of "D.N.A.", Obanazawa was in high school and went on a hike. He fell off a cliff but survived although his parents tell him that he was clinically dead for a moment.
Obanazawa once donated to the sperm bank a long time ago. At the time, he was 30 years old and live in a place called "Yamagata" although it isn't specified if it was the city or more broadly the prefecture. Mai underwent artificial insemination with his sperm and had Mao, a girl with strange characteristics and several unusual features like a vestigial tail and the ability to camouflage.
Obanazawa was also married and had a son named Tomoya. However, he and his wife divorced. Since then, Obanazawa has partial custody of Tomoya. Having passed the bar exam recently, Obanazawa currently works as a rookie lawyer in a firm in Yamagata city.
One day, Obanazawa fatefully meets Mai Katahira, the woman who used artificial insemination, in a train station. He briefly tells her that she can use the vending machine but leaves to pick up Tomoya at the park. Disturbed and suspecting that he's Mao's biological father, Mai follows him. At the park, Obanazawa picks up his son and calls a taxi so they can leave. As a prank, Mao has stuck her molted skin onto Tomoya and Mai is fooled into thinking that Obanazawa is kidnapping Mao. However, the misunderstanding is cleared and Obanazawa reassured Mai. When Mao speaks backwards, Obanazawa immediately understands that she's saying she's thirsty and hands her a can of soda he has bought earlier at the train station. Obanazawa, Mai, and their children decide to walk together, as the two parents begin to develop feelings for each other.
Less than 3 months afterward, Mai is stated to have married Obanazawa.
