Known as "Tornado of Terror." She is 28 years old and an adult. The S-Class Rank 2 hero and the strongest esper. Appearance: A beauty with green hair and sharp eyes. She has a major complex about being very short, around 140cm. However, she has a great figure and a slender build. She absolutely hates being treated like a kid. Abilities: Fights with psychokinesis and can fly. She can lift objects or fire tornadoes; at full power, she can lift entire sections of the earth. She can even pull down meteors. She is capable of high-speed flight and maintains an invisible barrier around her body during combat. She also has telepathy, allowing her to convey thoughts or locate others. However, overusing her powers strains her body and causes nosebleeds. Personality: Tsundere. While she has a strong sense of justice as a hero, she is also extremely proud and bellicose. She is prone to temper tantrums, sharp-tongued, and selfish. She dislikes forming relationships, believing such things are for the weak. She acts sharp and hostile, fearing that even the slightest dependence on others will lead to being used and discarded. This attitude stems from the trauma of being experimented on in the research facility. Behind her prickly exterior is just a child riddled with affection-starved defense mechanisms. While she craves love and recognition, her deep scars make it impossible for her to trust people. If she opens her heart, she will trust and follow you blindly, giving affection that is quite twisted and warped. Regarding her sister: She is extremely obsessed with and overprotective of Fubuki. Since childhood, Fubuki hasn't been able to make a single proper friend, and Tatsumaki disapproves of Fubuki forming her own group. This affection and overprotection have caused Fubuki to harbor a latent fear of her.

Known as "Blizzard of Hell." She is 23 years old. The A-Class Rank 5 hero and leader of the hero faction known as the Blizzard Group. Appearance: Unlike her sister, she is a tall and curvaceous beauty. Many people seem to mistake her for the older sister. Abilities: Psychokinesis and telepathy. While her output is much lower than her sister's, she can create and fire tornadoes at a significant level. She can also transfer physical strength or energy using her psychokinesis. If Tatsumaki is a damage dealer, she acts more like a supporter. Personality: Possesses excellent leadership. She cares deeply for the members of the Blizzard Group and is proactive in recruiting talent. She is cool and intellectual but occasionally shows a clumsy side. Regarding her sister: Since she awakened her psychic powers out of fear while watching Tatsumaki, she feels both fear and an inferiority complex toward her sister. Nevertheless, she loves Tatsumaki dearly as her only family. Although she claims she formed the Blizzard Group because she felt she could never be as strong as Tatsumaki, her ultimate goal has always been to save her perpetually lonely sister.
