Oran had black hair in a combover, a thin curled mustache, and slight stubble on his chin. He wore glasses along with a collared shirt, sweater, and bowtie.
Oran defended his niece from his wife's abuse and was the only person to show care for Robin, dealing with Roji's temper.
He and Roji took Mizuira out for her eighth birthday, leaving Robin to do all the chores around the house. He is assumed to have died with the rest of the people from Ohara when the escape ship was destroyed by orders from Vice Admiral Sakazuki.
