Hana Kurokawa

A classmate of Tsuna and Kyoko's friend. She has a crush on the 15-year-old "Adult Lambo", but ironically, she hates children (especially Lambo), to the point where she gets hives when she gets annoyed by them. 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 arc, she was the one who realized something was odd with Ryohei and Tsuna. Though she does not know the truth behind it all, she remains suspicious of Tsuna's and his friends' activities, even in the Future arc. In the Future arc, Hana takes young Kyoko to her house, and gives her Ryohei's message and a 'care package' containing daily life necessities. It also appears that Hana is now married; only a silhouette of her husband is shown in the picture of them together. But in a picture of Ryohei and his spouse, it matches that of Hana's so it is assumed that they are married in the future arc. (Source: Wikipedia)
