Though after the engagement party was crashed by Issei, he reflected on his mistake of forcing his beliefs onto his daughter. It was revealed that he also had great love for his daughter when she was very young. He and Sirzechs would cry with joy and have nosebleeds by looking at how Rias acted when she was an infant, and took many video recordings of Rias.
