Height 150 cm She is a fifteen-year-old student and a classmate of Ino at their high school. Coming from a wealthy family in Kanagawa, Hayu had decided to pursue becoming a musician against her father's wishes. As a result, she was forced to survive on her own at Nezumi House, and work as a talent for Rat Productions. Now a current member of Fruit Tart, Hayu helps write the group's song compositions along with Ino. While a terrible singer, Hayu is nevertheless passionate about working to become an idol. Charismatic and fun to be around, Hayu's tomboyish attitude perfectly matches her image as a rock musician. However, deep down she retains her feminine side, secretly reading comics for girls and holding on to her childhood dream of wanting to become a cute, blushing bride. Hayu's personality is thus a product of an overbearing mother and a father who had disowned her for wanting to write music. Like all the members of Fruit Tart, Hayu had lacked friends even while growing up and is thankful that she can confide her thoughts and feelings with Ino. However, Hayu is somehow sensitive to Ino's growing popularity as an idol, and has a fear of losing their close friendship to her adoring fans.
