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.
