Fubuki, operating as the B-Class Rank 1 hero Hellish Blizzard, commands the Blizzard Group faction composed primarily of B-Class heroes. She is the younger sister of Tatsumaki, the S-Class Rank 2 hero Tornado of Terror, and together they are known as the Psychic Sisters. Fubuki possesses significant psychic abilities, though notably weaker than her sister's, manifesting as telekinesis for levitating objects, manipulating earth and wind, generating barriers, and achieving flight through self-levitation. Originating from wealth, Fubuki endured bullying from her older sister during their youth due to her comparatively weaker psychic capabilities, fostering a lasting inferiority complex and hyper-competitive attitude. She deliberately maintains her position as B-Class Rank 1 rather than advancing to A-Class, believing she cannot reach the top of A-Class due to Sweet Mask, the A-Class Rank 1 hero who prevents others from advancing to S-Class. Her strategy centers on dominating B-Class and building the Blizzard Group, intending to surpass her sister through collective strength. Fubuki possesses light skin, green eyes, and black hair typically styled shoulder-length. She stands approximately 167 cm tall and favors a distinctive wardrobe: a form-fitting black dress, thigh-high boots, multiple bead necklaces, and often a white fur coat, reflecting her belief that "clothes define the person." Her personality exhibits ambition, strategic thinking, and leadership alongside insecurity and ego. Initially, she employs intimidation and force to suppress rising B-Class heroes and recruits promising ones into her group, viewing them as assets. Early interactions demonstrate conceit and a willingness to use violence to maintain control, such as confronting Saitama to coerce him into joining. When refused, she attacks him with telekinetic techniques and a razor blade, though these prove futile. Fubuki's character develops through interactions with Saitama and major conflicts. Observing Saitama’s power and his relationships with S-Class heroes like Genos challenges her worldview. She displays greater concern for subordinates, refusing to harm them when mind-controlled by the monster Do-S despite personal danger. During the Monster Association raid, she risks severe injury to stabilize Genos’s overheating core using her psychic energy suppression, earning his gratitude. These events signify a shift toward valuing teamwork and protection over dominance. Her relationship with Tatsumaki remains strained yet interconnected. Tatsumaki frequently criticizes Fubuki’s reliance on her group and mocks her defeats. Despite this, Tatsumaki consistently intervenes to protect her sister when seriously threatened. Fubuki both respects and resents her sister, yearning for acknowledgment while chafing under her control. A pivotal moment during the Monster Association arc sees Fubuki declare her intent to support Tatsumaki in ways her sister cannot achieve alone. Fubuki also harbors resentment toward Blast, the hero who saved Tatsumaki in their youth, believing his words left a detrimental psychological "curse" on her sister. Fubuki's psychic abilities encompass offensive, defensive, and supportive applications. Offensive techniques include "Hell Storm," generating a debris tornado; "Hell Cutter," launching concentrated telekinetic energy or ice shards; and "Hell Crush," manipulating large objects to crush targets. Defensively, she creates barriers capable of withstanding attacks from Dragon-level threats. Supportively, she demonstrates "Organic Healing" to stabilize injuries and "Psychic Binding" to immobilize groups. She can also fly and sense powerful psychic emanations. Beyond combat, Fubuki excels as a strategist and manager, organizing her group effectively and negotiating shrewdly. She handles the collateral damage from a battle between Saitama and Tatsumaki by accessing the Hero Association’s confidential systems to falsify reports, attributing the destruction to Demon-level monsters and crediting Tatsumaki with their defeat. This maneuver resolves legal and financial repercussions while benefiting her sister’s standing, underscoring her talent for behind-the-scenes problem-solving. Fubuki’s story arcs illustrate her progression from a self-interested leader fixated on status to a more collaborative hero who values allies and embraces supportive roles. She continues seeking Saitama’s affiliation, shifting tactics toward persuasion and bargaining information rather than force. She regularly visits his residence and participates in group activities, indicating gradual integration into his circle. Her commitment deepens, evidenced when she endures Do-S’s whip attacks to protect her mind-controlled subordinates.
