So far, Kenji has been shown to be a very, proud, caring and supporting father who loves his family very much and he is very enthusiastic about documenting his daughters' achievements by cutting out articles from news papers and magazines. At first it appears he is only enthusiastic about Chitose Ayase (Kenji's eldest daughter) and supporting her ambition of becoming a model, having already filled up to seven scrapbooks of her achievements. However, when Chihaya Ayase finds that the article about her karuta team heading to the nationals at Omi Jingu is missing from the newspaper at home, she finds that although he has only partially filled one scrapbook for her, he is in full support of her achievements and he is very proud of her.
