Haru Miura is a Midori Middle School student who likes Tsunayoshi Sawada. She is known for having a lot of costumes and disguises.
Haru is young teenage girl, with a slender and short build. She has black hair (changed to dark brown in the anime), which is always worn in a ponytail and tied up with green hair bobbles.
While consistently changing outfits in the series, her most promonient outfit is her Midori Junior High uniform. She wears a white formal shirt, a cream sweatervest with a blue bowtie, a gray skirt, black knee-high socks and brown shoes.
Her future counterpart has shorter hair, wearing a dark blue short-sleeved blouse and a white shirt underneath, a gray bracelet on her left arm, and black pants. While in the future, Haru is described as being more feminine compared to in her youth.
Haru is an upbeat and enthusiastic girl, living a mostly carefree life in Namimori, as well as being known to be somwhat of an airhead. Haru is well aware of Tsuna's status in the Mafia, although she doesn't know the complicated details and dreams to one day become the wife of a mafioso. Haru loves children and can become very protective towards them, especially towards Lambo and I-Pin, and dislikes the idea of children being involved in the mafia. She and Kyoko Sasagawa excel at cooking and housework very well.
While she is shown to be kind and caring, Haru is shown to be assertive in comparison to Kyoko, whenever Haru believes that Tsuna or Hayato Gokudera are doing something wrong she usually doesn't hesitate to scold them for their actions, and on certain occasions can lead to physical harm.
Haru has a fascination with costumes, which often lead to her changing into different costumes, which often bewilder Tsuna. She is also shown to be able to make dolls with her talented sewing skills.
According to Tsuna and Gokudera, Future Haru has become more feminine, but her way of thinking is still the same.
