Eiji is Mari's father—a brilliant scientist with a global reputation who's been missing for the past three years. He's the type of guy who's deeply devoted to his family, but his work has a way of consuming him. His curiosity doesn't have an off switch, which means his research tends to spiral and pull him under completely. There's something almost militant about his drive and discipline, but it all comes from a place of genuine care for the people closest to him. The three-year disappearance has obviously cast a long shadow, though exactly what happened remains unclear.
