02Appearance
Obanazawa is a tall and athletic Japanese man with messy curly black hair, thick eyebrows and a distinctive scar on his forehead. He has no upper eyelashes, thick lower eyelashes, and sideburns that grow to his jaw.↗
He dresses in a long sweater and black pants, carrying a large backpack with him. He has an abnormal quirk where his feet are soaking wet when he walks, which Mao inherits.↗
03Personality
Obanazawa is calm and gentle. He is aware that he may look intimidating because of the scar on his forehead and tries comforting Mai Katahira to not be afraid of him. He is friendly with children such as his biological daughter Mao. He manages to comprehend her abnormal manner of speech, and can even make her speak coherently afterwards.↗
After falling off a cliff on a hike during his high school years, Obanazawa no longer does anything dangerous. He doesn't drive either, and calls a taxi instead.↗
They both have a habit of scratching their eyebrows with their little finger, licking their lips, and opening a can of soda with their little finger.↗
04Story
SPOILERS
Background
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 three years prior to the story. At the time, he was 30 years old and lived in Yamagata City. Mai Katahira underwent artificial insemination with his sperm and gave birth to 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.↗
Deoxyribonucleic Acid
One day, Obanazawa fatefully meets Mai at S City Station. He briefly tells her that she can go ahead of him to use the vending machine and then leaves to pick up Tomoya at the park. 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 used her camouflage ability to make Tomoya look like her, fooling Mai into thinking that Obanazawa is kidnapping Mao.↗
Less than 3 months afterward, Mai is stated to have married Obanazawa.↗
