Similar to his great-grandfather, Yoshiteru is somewhat exaggerated in regards to his reactions. When he was reading the book which explained the battle against Muzan Kibutsuji, he began crying over his ancestor's determination and willingness to risk their lives. Yoshiteru has also expressed the flirtatious tendencies of his ancestor as he was seen gawking at female students. Despite his flirtatious behavior, Yoshiteru is submissive to his sister and is somewhat afraid of her.
