Hana Sugurono, a 17-year-old from Setagaya, Tokyo, combines a tomboyish demeanor with fierce independence, shaped by childhood wilderness training under her father. Her survival expertise—honed through rock climbing, swimming, and camping—proved vital after awakening in a ruined world as part of Team Spring. A near-drowning at age 10 bound her to rescuer Arashi Aota, their bond deepening into romance, while her parents’ secret involvement in Project 7 Seeds remained obscured by emotional distance. She once confused temporary guardian Kaname for her father due to their resemblance, a connection later tested when he nearly euthanized her during her battle with Redskin Disease, a fungal ailment she overcame through solitary saltwater treatment.

Her resilience faced brutal trials: surviving misogynistic guide Yanagi’s attempted assault, his subsequent death by parasitic wasps, and fleeting suicidal despair dispelled by clues of Arashi’s survival. Temporary amnesia after a river ordeal reduced her to a childlike state, fostering unexpected bonds with wild animals—a boar family, a rescued foal—despite no prior pets. Practicality drove her to cut her hair, masking insecurities over her changing body and envy of others’ looks.

Leadership emerged reluctantly, her bluntness clashing with teammates even as she mastered free-climbing cliffs, crafting bamboo weapons, and navigating lethal ecosystems. A complex dynamic with Aramaki, marked by unspoken attraction conflicting with loyalty to Arashi, led her to prioritize his emotional stability during crises. Her accidental release of invasive shiitake spores devastated a forest, a disaster mitigated only by the sacrificial deaths of Aramaki’s dogs—a harsh lesson in consequence.

Adapting to the transformed world, she balanced self-reliance with fragile trust in allies, clinging to hope for Arashi’s return while navigating grief, guilt, and the raw demands of survival.
