Otome's younger sister and non-blood-related younger sister of Yoshiyuki, who looks very much like Nemu in her youth, which isn't surprising, considering that Nemu is her grandmother. As a child, Yume was friendly and cheerful girl, but after growing up she became lazy and grumpy, having inherited a habit of saying "What a pain in the neck" from her grandfather, Jun'ichi. However, she acts like that only at home.
At school, she is popular among the boys. Maybe her character is influenced by the special feelings that she has for her brother, but can't reveal them to him. And the magic cherry tree gave her a special gift, which eats her from the inside.
