The maternal grandfather of Misaki's mother Kaoru, who left his house to Misaki upon his death. He had a history in genetic science but gave it up to take care of his family and research evolution. He had a vast collection of animal, plant, and dinosaur fossils which he gifted to a nearby museum in exchange for writing off the inheritance tax Misaki would have to pay on his house. His discovery of an ancient dinosaur skeleton near the lake made him famous as a paleontologist.
