Tsunagu Hakamada, the Pro Hero Best Jeanist, features a tall, slim frame, an unnaturally long and flexible neck, and dark eyes with heavy lashes. His signature look includes dramatically left-combed blond hair covering one eye and a custom denim hero costume. This costume evolved from an initial design of a denim waistcoat, high-collared dress shirt obscuring most of his face, jeans, dual belts, and boots. Later versions adopted darker tones, redesigned belts bearing his hero initials, longer boots, and eventually a laced neck with baggier sleeves, balancing practicality and aesthetics. Denim remains the core material to maximize his Quirk's effect. He embodies a flamboyant yet disciplined personality, insisting elegance in appearance and conduct is vital for influential figures. Tsunagu frequently uses sewing and fabric metaphors, advising others to "keep their life straight like their jeans." He holds deep convictions about heroism as selfless service dedicated to public safety and peace, driving acts like intercepting All For One's attack despite severe injury. He openly disdains brutish behavior, evidenced by his frustrated attempts to reform Katsuki Bakugo's aggression during an internship. Yet, his reputation as a skilled youth counselor endures, surprising peers like Gang Orca when Bakugo resisted his influence. His Quirk, Fiber Master, grants telekinetic control over fibers in fabrics and materials like carbon fiber. Denim responds best, while sweats prove difficult. Primary applications include restraining targets by unraveling his costume or manipulating opponents' clothing, forcing evasive maneuvers for allies, and creating safety nets. Notable techniques encompass the suffocating "Blackout Bind," rescue-focused "Catching Cradle," and large-scale immobilization "Thread of Hope." Against powerful foes like Gigantomachia, he supplements with industrial-strength fiber cables. Mastery demands intense focus and years of training; lapses weaken efficacy. All For One notably avoided stealing it due to its complexity. Tsunagu attended U.A. High, founding the "Textile Arts Association" with Shinya Kamihara. As a Pro Hero, he consistently ranked in Japan's top five, rising to No. 3 after All Might's retirement. Early exploits involved responding to Instant Villain outbreaks in Naruhata and aiding at Captain Celebrity's Tokyo Sky Egg farewell. During the Sky Egg terrorist attack, he helped secure the collapsing structure using carbon fiber cables. He later collaborated with heroes like Edgeshot to apprehend the vigilante Koichi Haimawari (The Crawler), acknowledging Koichi's heroism at Sky Egg. Amid the Naruhata Lockdown's citywide blackout and villain attacks, he reassured citizens and performed rescues despite injury from trap villains. During Bakugo's internship, Tsunagu critiqued the student's post-Sports Festival conduct, striving to instill ideals of appearance, speech, and emotional control. Though Bakugo resisted grooming and lectures, he later respected Tsunagu, revising his hero name per his suggestion. In the Hideout Raid, Tsunagu restrained multiple Nomu and briefly immobilized All For One, sustaining grievous injuries including lung loss when All For One broke free, forcing months of recovery. He later faked his death via medical procedure to deceive Dabi, resulting in severe physical weakening. He returned dramatically during the Paranormal Liberation War, binding key villains including Tomura Shigaraki and Gigantomachia despite visible strain. In the Final War, he led a hero team against Shigaraki at U.A. Fortress. Post-war, his public rapport proved vital amid eroded hero trust. He successfully convinced civilians to relocate to U.A.'s safehouse, functioning as an unofficial Symbol of Peace. His endorsement of Deku boosted public acceptance of the young hero. Eight years later, he continued hero work with a modified costume and hairstyle, reflecting ongoing adaptation.
