Himawari Kunogi, a high school student radiating cheerful energy, sports long curly hair often tied into playful pigtails and a constant smile concealing her secret awareness of the misfortune trailing those near her. Born into a family entwined with the occult, she harbors an inborn curse of calamity—arson, suicides, and fatal accidents plague anyone unprotected by spiritual resilience, sparing only her parents and those with mystical defenses. This relentless string of tragedies fuels her guilt, driving her into self-imposed solitude to shield others. Her bond with classmate Kimihiro Watanuki blossoms as he finds solace in her warmth, nurturing unspoken romantic feelings. Though feigning ignorance, Himawari recognizes his affection and deliberately maintains emotional distance to spare him harm. Their encounters frequently strand Watanuki alongside Shizuka Dōmeki, whose spiritual aura nullifies her curse. A defining moment arrives when Watanuki plummets from a school window under her curse’s sway. To rescue him, Himawari absorbs his physical wounds, hiding the scars beneath loosened hair—a transformative act deepening her resolve to withdraw. Yet Watanuki’s insistence on connection compels her to cautiously sustain their friendship, balancing closeness with protective guilt. The curse weakens when Watanuki gifts her Tanpopo, a mystical bird hatched from an egg tied to supernatural crossovers, immune to her ill fortune. Over time, mutual romantic feelings flicker between Himawari and Watanuki, but she ultimately weds an unnamed businessman tolerant of their bond. Post-Watanuki’s inheritance of Yūko Ichihara’s supernatural shop, Himawari avoids direct visits, confining contact to yearly birthday meetings and sparse calls to evade reigniting disasters. In later narratives like the OVA *Rō Adayume*, her physical absence looms as Dōmeki delivers her wedding invitation to Watanuki, cementing her departure from supernatural entanglements. Her legacy lingers through the lasting echoes of her curse’s ripple effects—strained bonds, irreversible choices, and the enduring marks left on Watanuki and Dōmeki’s intertwined fates.
