Fubuki, operating under the hero alias Blizzard of Hell, holds the rank of B-Class Rank 1 in the Hero Association. She is a powerful esper wielding psychokinetic abilities and founded the Blizzard Group, a faction of B-Class heroes designed to consolidate her influence. As the younger sister of Tatsumaki, the S-Class Rank 2 hero Tornado of Terror, Fubuki shares the designation of Psychic Sister. Her motivations are deeply shaped by this relationship, constantly overshadowed by her sister's vastly superior power, fueling persistent feelings of inferiority and insecurity. Her appearance emphasizes status and professionalism. Fubuki maintains an elegant, confident demeanor with a chin-length dark green bob and emerald green eyes. She typically wears a form-fitting green dress, thigh-high boots, pearl necklaces, and a distinctive white fur coat, embodying her belief that "clothes define the person." This meticulous presentation bolsters her image as a charismatic leader. Fubuki's personality blends ambition, strategic thinking, and underlying vulnerability. Initially employing intimidation to recruit heroes into the Blizzard Group, she aimed to dominate B-Class and shield her faction from higher-tier competition, partly driven by Sweet Mask's gatekeeping in A-Class. Despite her authoritative exterior, she demonstrates loyalty to her members and gradually develops a more selfless outlook. Her encounter with Saitama marks a turning point, challenging her reliance on collective strength and prompting introspection about her self-worth independent of Tatsumaki. This catalyzes her evolution from a rival-focused leader to one valuing mentorship and ally protection. Her psychokinetic abilities cover offense, defense, and support. Key techniques include the offensive Hell Storm, summoning debris tornadoes; defensive Psychic Barriers capable of blocking Dragon-level energy attacks; the healing power Organic Healing; and immobilization via Psychic Binding. Fubuki demonstrates precise control under pressure, such as stabilizing Genos' overheating core through energy suppression. While her raw power falls short of Tatsumaki's, she exhibits refined directional control to withstand high-level threats. Her prowess is acknowledged as A-Class caliber, yet she deliberately remains in B-Class to maintain leadership of her group and avoid direct competition with her sister. Throughout major story arcs, Fubuki emphasizes strategic leadership and gradual growth. Her introduction involves attempting to forcibly recruit Saitama, abandoning the plan after witnessing his strength. She instead incorporates him into an informal "Saitama Group," reflecting her shifting perspective on alliances. During the Monster Association raid, Fubuki risks her life shielding allies like Bang and Bomb from Overgrown Rover using her barriers, showcasing developing selflessness. The Psychic Sisters arc explores her strained relationship with Tatsumaki, culminating in Fubuki confronting her sister's isolationist tendencies and resolving to support her despite their differences, highlighting her journey toward reconciling ambition with familial bonds. Fubuki's background involves latent psychic abilities manifesting alongside Tatsumaki's, though she lacked her sister's early combat exposure, contributing to lifelong inadequacy. Four years prior to the main events, she formed the Blizzard Group partly to assert independence. Her refusal to advance beyond B-Class stems from maintaining control over her faction, avoiding Sweet Mask's scrutiny in A-Class, and internalized fears of inadequacy in higher ranks, defining her strategic choices and personal conflicts.
