He debuted in the chapter 131 of To Love Ru, and plans Saki transfer to foreign school for abroad study without her consciousness. But Saki behaves resistant to father and runs away home although she usually complies with him. He brings her back to home as she shows reluctance to his plan. In chapter 132, he appears to talk to Kai, and tells that he had a conversation with Saki. She came out him that she won't separate Rin and Aya who are important for her, and Saki had never revealed it before. His plan for Saki's abroad study is cancelled. Saki had matured, and began to laugh and said that she was logical since being his daughter. In the final, he said Kai that he didn't like the rancour that his daughter had towards him.
