Haru is the girl who likes Tsuna, and attends Midori Middle School, one of the toughest elite schools to get into in the area. She initially adored Reborn, but after she was saved by Tsuna, she diverted her adoration towards him instead. She loves children and is usually the one to babysit Lambo and I-Pin.
According to Tsuna and Gokudera, adult Haru has become more feminine, but her way of thinking is still the same.
After Reborn told Haru of the devastation in the future, hiding from her details about the Mafia, Haru seems to lose her calm and cries, begging to be taken back home, leading Kyoko to comfort her.
During an argument, Tsuna tells her that she does not understand anything, but Haru states that she is always there to listen, and that Tsuna has never tried to explain anything. Though she leaves the room crying, they later reconcile after Tsuna apologizes.
