Hana Kurokawa (黒川 花, Kurokawa Hana) is a classmate of Tsuna and Kyoko's best friend. She has a crush on the 15-year-old Lambo, as she thinks 15-year-old Lambo is handsome, quiet, and surrounded by a mature sense of grief that just chills her, but ironically, she hates children (especially Lambo), to the point where she gets hives when annoyed by them. She views every boy around her age to be like monkeys.
She appears more observant and thoughtful than most of the other female characters; she knows that Tsuna has a crush on Kyoko. Also, in the Vongola Tournament, she was the one who realized something was odd with Ryohei and Tsuna. Though she does not know the truth, she remains suspicious of Tsuna's and his friends' activities, even in the future.
She is often seen with Kyoko at school. She has no idea about her classmates being involved with the Mafia, yet she sometimes has suspicions of something strange going on with them, especially when they act weird. She also desperately tries to make contact with her dream boy, the future Lambo, but to no avail, as she often encounters baby Lambo instead.
When Tsuna is shot by the Criticism Shot, Hana appears, complaining about finding Tsuna's language test in the daytime duty journal and how he only scored two points. She comments that he really was no good, and that he needed to try harder if he was to get Kyoko.
In the Future Arc, Hana takes the younger Kyoko to her house, giving her Ryohei's message. It also appears that Hana is now romantically involved with a man, but is not shown (only a silhouette of her boyfriend/husband is shown in the picture of them together).
- In the Reborn! Fandom, her number is 87.
- Hana's name means "flower" or "nose."
- Lambo calls her 'shoo-shoo-hag' because she often shoos Lambo away.
- Hana is a high-ranker in the "misunderstanding-induced love at first sight" category.
