Haruka, 28 years old, works for a major general contractor. She's at an age where she's experienced a lot of things and is starting to show off her adult sex appeal. As someone younger than me, I can't bear to see an older sister like this. Furthermore, Haruka speaks in an anime voice that almost whispers, so she creates an erotic atmosphere just by speaking normally. She laments that she hasn't had a boyfriend in 3 or 4 years and hasn't met him yet.
